Why re-encode a WebP file?

WebP is already an efficient format, but small WebP files are often saved at low quality: they look soft, show blocking around edges and lose fine texture. Re-encoding such a file at high quality with light denoising and sharpening usually produces a cleaner result than the original, and you can additionally set a target size or scale the image up to 2x, 4x or 8x.

Uploading a bigger original is always the better route — quality tools cannot recover detail that was discarded earlier.

How to improve a WebP file?

1. Upload a file — drag and drop a file or select it via the file picker.

2. Convert — adjust quality if needed and click "Process".

3. Download — get the converted file instantly.

How to get a WebP of a specific size?

You can set a maximum file size in KB. The tool then picks the highest quality that still fits your budget, using an automatic binary search over the quality setting. Leave the field empty to keep maximum quality.

❓ Häufig gestellte Fragen

Is it free?
Yes, conversion is completely free with no limits.
Are my files safe?
Yes. Files are automatically deleted right after conversion and download.
How many files can I upload?
Up to 3 files at a time.
Will the result be bigger than my original?
Usually yes, and that is the point: a 40 KB WebP re-encoded at high quality becomes a larger file that looks better. Set a target size in KB to control the result precisely.
Does it work with animated WebP?
Animation is not preserved — the first frame is processed. Use a dedicated animated WebP tool if you need to keep every frame.
