Frequently Asked Questions

No. WeblixTools processes 100% of your assets entirely within your browser using client-side HTML5 Canvas and JSZip. No images, text strings, or design data are ever transmitted, stored, or analyzed remotely.

Simply drop icon.svg and apple-icon.png directly into your app/ folder. Next.js automatically detects these files and generates the matching metadata tags in your HTML output without any manual configuration.

SVG favicons are resolution-independent vectors that remain tack-sharp on 4K, 5K, and 8K monitors while consuming less than 1 kilobyte of bandwidth. Crucially, SVGs support internal CSS media queries to automatically change colors when users toggle dark mode.

Browsers cache favicons aggressively. During development, add a cache-busting query parameter (e.g., /icon.svg?v=2) or clear browser cache specifically for host assets in Chrome DevTools under Application → Storage → Clear site data.

Yes! All generated files and assets are 100% royalty-free and yours to use for personal, open-source, client, or enterprise commercial products with zero restrictions.

Yes. Each visitor gets a number of free AI generations per day. Customising the icon and exporting favicons in the Studio is always free and unlimited.

You can use icons you generate for your own websites, apps and client projects. Avoid prompts that copy existing trademarks or logos, as the AI may reproduce protected designs.

Name the main object, what your product does and the mood you want, for example “a paper plane inside a circle for an email app, friendly and modern”. Short, concrete descriptions work best.

A symbol on a plain background is easiest to customise: the Studio adds a squircle, circle or rounded background with your own gradient, so the icon matches your brand on every platform.

You can download the generated image directly, or open it in the Studio to export favicon.ico, PNG favicons, a dark-mode SVG favicon, Apple touch icons, Android adaptive icons and a web manifest.

Your description is sent to our AI provider to create the image and kept briefly in our logs to prevent abuse. Don't include personal or confidential information.

The generated SVG file embeds a @media (prefers-color-scheme: dark) stylesheet directly in the vector markup. Browsers evaluate this CSS dynamically to switch icon colors instantly.

Yes, keep it as a fallback. Older browsers and some crawlers still request /favicon.ico, so the download includes a multi-size ICO alongside icon.svg.

Browsers cache favicons aggressively. Hard-reload the page or add a version query such as /icon.svg?v=2 to the link tag after you replace the file.

Modern browsers evaluate embedded CSS media queries inside the SVG file to select the active fill color based on the user's OS preference.

Browsers that render SVG favicons (Chrome, Edge, Firefox and recent Safari) evaluate the media query inside the file. Others fall back to your ICO or PNG, which uses a solid tile so it stays visible in both themes.

Yes, but check the dark preview carefully. A transparent icon with dark artwork is exactly the case that disappears on dark tabs.

Yes, our tool rasterizes the emoji into crisp PNG and ICO assets for legacy browsers while also creating a vector SVG for modern browsers.

Emoji characters are a Unicode standard, but the artwork belongs to each platform vendor. For a commercial brand, consider using the emoji only as a placeholder until you have your own mark.

The PNG and ICO files are drawn with the emoji font of the device that generated them. Generate on the platform whose emoji style you prefer.

You can set the letter colour, the background colour or gradient, the corner radius and the padding. Letters are drawn in your system's bold sans-serif font so they stay crisp at 16×16.

One is ideal and two is the practical maximum. At 16×16 pixels each letter gets only a few pixels of width, so three or more letters become unreadable.

Yes. Switch the studio to Upload Logo to use a PNG, JPG, WebP or SVG file. It is processed entirely in your browser.

Maskable icons include extra safe-zone padding so the Android launcher can crop them into circles, squircles, or rounded rectangles without clipping the logo.

Keep the important artwork inside the centre 80% circle. In practice a padding of about 10–15% in the studio keeps most glyphs safe on every launcher shape.

The bundle includes ic_launcher PNGs and PWA manifest icons. For a native Android app, use Android Studio's Image Asset tool to build separate foreground, background and monochrome layers from the 512 px PNG.

Place favicon.ico, icon.svg, and apple-icon.png directly in your /app root directory. Next.js handles serving and caching automatically.

Delete any old favicon.ico in public/ (it can shadow the app/ version), restart the dev server and hard-reload. Browsers cache favicons for a long time.

Yes. Next.js supports app/icon.tsx with ImageResponse, but a static icon.svg is smaller, supports dark mode and needs no server rendering.

In iOS 18, users can customize their home screen by tinting all app icons with an accent color. Apple recommends providing a high-contrast monochrome version to prevent automated clipping artifacts.

No. Xcode 14 and later accept a single 1024×1024 image per appearance and generate the smaller sizes at build time, which is the format this tool exports.

Yes. App Store icons must be opaque. Keep a solid background colour or gradient for the iOS export.

No. The tool runs entirely in your browser tab. Your images never leave your device, and closing the tab discards them.

HEX (like #4F46E5), RGB (rgb(79, 70, 229)) and HSL (hsl(243, 75%, 59%)). Click the copy button next to any of them.

The tool groups similar pixels together and shows the most common distinct colours, ordered from most to least used. Tiny details and transparent pixels are ignored.

Yes, in Chrome and Edge on desktop: click Pick from screen and then click anywhere on your screen. Other browsers don't support this yet.

No. The tool runs entirely in your browser tab. Your images never leave your device, and closing the tab discards them.

75–85% is a good balance for photos and website images. Go higher for images with fine text or sharp edges, lower if file size matters most.

PNG is lossless, so it can only be re-packed, not reduced in quality. Convert it to WebP for a much smaller file that keeps transparency, or to JPG for photos.

Yes. Re-encoding drops hidden metadata such as camera details and GPS location, which also makes the files more private to share.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

Yes. Choose Edit text and click a line. The editor covers the original words and writes your new text in the same position, size and colour, using the closest standard font (Helvetica, Times or Courier). It works best for short changes like names, dates and prices; scanned pages have no editable text.

Real, selectable text for Latin letters and numbers. Text in scripts the standard PDF fonts don't cover, like Urdu or Arabic, is added as a sharp image so it still looks right.

Yes. Use the Undo and Redo buttons or Ctrl+Z and Ctrl+Y. Nothing is saved into the PDF until you click Download.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

It is a simple electronic signature, which many countries accept for everyday agreements. Some documents need a certificate-based digital signature or a handwritten one; check what the recipient requires.

Yes. Draw the signature with your finger, then drag it into place on the page.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

Yes. Click anywhere on the page with the Add text tool and type. You can change the size and colour of the text to match the form.

Answers typed into the form's own fields stay in those fields. Text added with Add text becomes part of the page.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

There is no fixed limit. Very large merges use more memory, so if your browser slows down, merge in smaller batches and then merge the results.

No. Pages are copied without re-compressing, so the merged file looks exactly like the originals.

Protected PDFs must be unlocked first. Open them with the password in your PDF reader, save a copy without protection, then merge that copy.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

No. Pages are copied exactly as they are in the original file, including vector text and embedded images, so there is no quality loss.

Separate ranges with commas. "1-3, 7, 10-" creates three PDFs: pages 1 to 3, page 7, and page 10 to the end of the document.

Not directly. Encrypted PDFs must be unlocked first. Open the file in your PDF reader with the password, save a copy without protection, then split that copy.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

Yes. Deleted pages stay in the grid, faded, until you download. Click the restore button on a page to bring it back.

No. Rotation only changes how the page is displayed. The page content is not redrawn.

The organizer shows up to 300 pages. For longer documents, split the file first, organize each part, then merge them back together.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

Yes. The new orientation is saved into the PDF, so it opens rotated in every viewer.

Yes. Select some pages, choose an angle, and rotate them. Then select other pages and rotate them by a different angle before downloading.

Use PNG for text-heavy pages and diagrams, JPG for scans and photos, and WebP when you want the smallest files for the web.

150 DPI suits most uses. Choose 300 DPI for printing or zooming into fine detail, and 72 DPI for quick, lightweight previews.

There is no fixed limit, but very large documents at 300 DPI use a lot of memory. If your browser slows down, convert fewer pages at a time or lower the resolution.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

No. JPG images are embedded without re-encoding, and PNG and WebP images are stored losslessly.

Phones often save photos sideways and add a note saying how to rotate them. Many converters ignore that note. This tool reads it, so photos appear upright in the PDF.

Use A4 (most of the world) or Letter (US and Canada) for documents you will print or upload to forms. Use Fit to image for screenshots and designs.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

Yes. Tick "Skip the first page". Numbering then begins on page 2, starting from the number you set.

Numbers and Latin text such as "Page" or "Seite" are supported. Scripts like Arabic, Urdu or Chinese are not available in the built-in PDF font.

No. The tool runs entirely in your browser tab using JavaScript. Your files never leave your device, and closing the tab discards them.

A determined person with PDF editing software can remove any text watermark. Tiled watermarks are much harder to remove cleanly than a single stamp.

Latin letters, numbers and common punctuation are supported. Scripts like Arabic, Urdu or Chinese are not available in the built-in PDF font.
