About Image to WebP
WebP is the modern successor to JPG and PNG that most websites have quietly adopted over the last few years. The format produces smaller files than JPG at the same visual quality (typically 25–35% smaller), supports transparency like PNG, supports both lossy and lossless modes, and is now decoded natively by every browser shipped in the last seven years. Image to WebP converts JPG, PNG, GIF, BMP and TIFF files into WebP for size savings without quality loss.
The tool exposes both WebP modes. Lossy WebP works like JPG but with a smarter compression algorithm — at quality 80 you get files roughly 25–35% smaller than equivalent quality-80 JPGs, with no perceptible visual difference. Lossless WebP works like PNG but with much tighter compression — typically 25–40% smaller than the equivalent PNG, with byte-exact pixel preservation. The default mode picks lossy for JPG inputs and lossless for PNG/GIF inputs, which is right for most use cases; you can override per file.
The most concrete reason to convert to WebP is page speed. Moving a typical image-heavy webpage from JPG to WebP drops the total image weight by 30–40%, which translates directly into faster Largest Contentful Paint scores in Core Web Vitals. The same logic applies to mobile apps that include bundled image assets, email templates where attachment size matters, and any storage system where you pay for bytes used. WebP’s transparency support also means you can replace PNG illustrations with WebP files at a fraction of the size.
Compatibility is essentially solved at this point — Safari, Chrome, Firefox and Edge all support WebP out of the box. The remaining cases where WebP is risky are systems that explicitly check the file extension (a few legacy CMSs) or some printing services that have not added WebP support. For those destinations, stick with JPG or PNG. Everywhere else, WebP wins on size with no visible quality cost. The conversion runs entirely in your browser; nothing is uploaded.
How it works
- 1Drop your images. JPG, PNG, GIF, BMP and TIFF are all supported up to 50 MB each.
- 2Pick the WebP mode: lossy (default for JPG inputs) for smaller files, or lossless (default for PNG/GIF) for byte-exact output.
- 3For lossy mode, choose a quality level. 80 is the recommended default; 70 for max savings, 90 for archival quality.
- 4A live preview shows the WebP output at the current settings alongside the projected file size.
- 5Hit Convert. Each image is decoded and re-encoded as WebP using the browser’s built-in WebP encoder.
Common use cases
- Convert hero images to WebP to improve Largest Contentful Paint on a marketing page
- Replace heavy PNG illustrations on a website with smaller transparent WebP files
- Bundle smaller images in a mobile app or PWA without losing visual quality
- Reduce the size of a photo gallery for faster loading on slow mobile connections
- Convert a folder of camera JPGs to WebP for an archive where storage cost matters
- Swap PNG product images on an e-commerce site to WebP for a 30% bandwidth reduction
FAQ
What is WebP?
WebP is a modern image format developed by Google that provides superior lossless and lossy compression.
Is WebP supported everywhere?
All major browsers support WebP. Some older software may not open WebP files.
How much smaller are WebP files?
WebP files are typically 25–35% smaller than equivalent JPGs and PNGs at the same visual quality.
Is WebP supported in every browser my visitors will use?
Essentially yes. Safari (since 14), Chrome (since 32), Firefox (since 65), Edge (since 18), and every mobile browser shipped in the last seven years all decode WebP natively. The only exception is users on truly ancient browsers (IE11, Safari 13 or older) — for those you would serve a JPG/PNG fallback via a <picture> element. Most modern CMSs and frameworks handle the fallback automatically.
How much smaller are WebP files compared to JPG or PNG?
Lossy WebP at quality 80 is typically 25–35% smaller than JPG at quality 80 with no perceptible visual difference. Lossless WebP is typically 25–40% smaller than PNG for the same exact pixels. For images with a mix of photographic and graphical content, the savings can be even larger — WebP’s compression handles both types well.
When should I pick lossless WebP over lossy?
Use lossless when pixel-exact preservation matters — UI screenshots, line art, technical diagrams, anything that will be edited further, or anywhere you would normally use PNG. Use lossy for photographic content, hero images, and anything where the file-size savings matter more than absolute fidelity. The default picks lossy for JPG inputs and lossless for PNG/GIF inputs, which matches what most people want.
Does WebP support transparency?
Yes — both lossy and lossless WebP support full alpha-channel transparency, just like PNG. This is a major reason to switch from PNG to WebP for transparent illustrations on websites: you get the same transparency at much smaller file size.
What WebP quality should I use for web images?
Quality 80 is the right default — files are 25–35% smaller than equivalent JPGs with no perceptible visual loss. For maximum performance on mobile (where every kilobyte of bandwidth matters), drop to 70. For archival or print-quality output, push to 90. The live preview lets you see the trade-off before committing.
Can I convert animated GIFs to WebP?
Animated WebP exists, but the current Image to WebP tool converts only the first frame of an animated GIF (because animated WebP is not yet uniformly supported in image editors and CMSs). For full animation, the GIF Maker tool produces optimised animated GIFs, or convert to MP4 video for the most efficient animation format.
Is the conversion lossless going from PNG to lossless WebP?
Yes — every pixel of the PNG is preserved byte-exactly in the lossless WebP output. The only difference is the file size, which is typically 25–40% smaller because WebP’s lossless compression is more efficient than PNG’s.
Can I convert WebP back to JPG or PNG later?
Yes — most modern image tools accept WebP input. If you need to convert WebP to JPG or PNG specifically, use the Image to PDF tool reversed or work in any modern image editor that supports WebP. Lossless WebP → PNG is exact; lossy WebP → PNG preserves the WebP-quality output but cannot recover detail discarded in the original lossy step.
