Why use WebP compression?
WebP is a modern image format developed by Google that achieves significantly smaller file sizes than JPG and PNG while maintaining comparable visual quality. It supports both lossy and lossless compression, as well as alpha channel transparency.
WebP vs JPG vs PNG — size comparison
- WebP lossy is ~25–35% smaller than JPG at equivalent visual quality
- WebP lossless is ~26% smaller than PNG
- WebP supports transparency (unlike JPG)
- All modern browsers support WebP: Chrome, Firefox, Safari 14+, Edge
Best use cases for WebP
- Website images — fastest loading times, best Core Web Vitals scores
- Product photos in e-commerce — smaller files, faster pages, more conversions
- Blog post images — WebP reduces bandwidth without sacrificing quality
- Converting old JPG/PNG assets — compressing to WebP is a quick win for any website
Quality settings for WebP
A quality setting of 75–85% gives the best balance of file size and visual fidelity. At 80% quality, WebP images are typically 3–5× smaller than their original JPG equivalents. For images where quality is critical (portfolio, product photos), stay at 85–90%.
Frequently Asked Questions
Are my files uploaded to a server?
No. All compression happens directly in your browser using the Canvas API. Your files never leave your device — no uploads, no server processing, 100% private.
Can I compress multiple files at once?
Yes. Drop as many files as you need and click "Compress all" to process everything at once. Click "Download all" to get a single ZIP archive with all compressed files.
How much smaller is WebP compared to JPG?
WebP is typically 25–35% smaller than JPG at equivalent visual quality. A 1 MB JPG compressed to WebP at 80% quality usually lands around 300–500 KB.
Do all browsers support WebP?
Yes — WebP is supported by all modern browsers: Chrome, Firefox, Edge, Opera, and Safari 14+. For broader compatibility with older Safari versions, you can use the <picture> element with a JPG fallback.
Does WebP support transparency?
Yes. WebP supports alpha channel transparency, making it a direct replacement for PNG in most cases while achieving smaller file sizes.
What quality setting should I use for WebP?
75–85% is ideal for web use — it cuts file size dramatically with minimal visible quality loss. Use 85–90% for portfolio or product images where fidelity matters. Go as low as 60–70% for thumbnails and previews.
Can I compress JPG or PNG files to WebP?
Yes. Drop any image format — JPG, PNG, GIF, BMP, AVIF, TIFF — and this tool will compress and convert it to WebP. This is one of the best ways to reduce image weight for websites.
Is WebP compression lossy or lossless?
WebP supports both. This tool uses lossy compression with an adjustable quality slider, which gives the smallest file sizes. For truly lossless WebP, set quality to 100%, but file sizes will be larger.
Can I preview the compressed WebP image before downloading?
Yes. After compression, a thumbnail of the result appears in the Preview column. Click it to open a fullscreen view so you can compare quality before downloading. If needed, adjust the quality slider and re-compress.
