Compress WebP Online Free
WebP already produces smaller files than JPEG and PNG, but you can compress WebP images further. FastEdit lets you re-encode WebP files with different quality settings, switch between lossy and lossless modes, or use fit-to-size to hit a precise target, all in your browser, with no upload.
How to finish the file
- 01
Open FastEdit
Go to app.fastedit.net. Everything runs locally in your browser, no signup or install.
- 02
Load your WebP file
Drag and drop your WebP image onto the editor. It stays on your device, no server involved.
- 03
Select compression mode
Choose lossy for maximum size reduction or lossless to preserve every pixel. Lossy WebP at quality 75-85 is typically 25-35% smaller than equivalent JPEG.
- 04
Adjust quality or use fit-to-size
Fine-tune the quality slider, or enable fit-to-size and enter your target file size. FastEdit iterates automatically to hit the target.
- 05
Compare and export
Use side-by-side comparison to verify the result, then export your compressed WebP.
Benefits
- WebP is 25-35% smaller than JPEG at equivalent visual quality, and compressing further multiplies savings.
- Supports both lossy and lossless modes in a single format.
- Full transparency support (8-bit alpha) unlike JPEG.
- Animation support makes WebP a superior GIF replacement.
- All modern browsers support WebP including Safari, Chrome, Firefox, and Edge.
Compression Tips
- Lossy WebP at quality 75-85 is typically 25-35% smaller than an equivalent JPEG at the same visual quality.
- Lossless WebP is 20-25% smaller than lossless PNG for the same image, useful when you need pixel-perfect output.
- WebP supports both animation and transparency, making it a versatile replacement for GIF and PNG.
- All modern browsers support WebP. The only notable holdout was Safari, which added support in version 14 (2020).
Shrink the file, keep the quality in sight, and never hand over the original.
