Frequently asked questions
Which formats can I compress?
JPG/JPEG, PNG and WebP. The compressor keeps each image in its original format — it never silently converts it. To convert between formats, use the Photo Editor.
Are my images uploaded to a server?
No. All compression runs locally in your browser, so your images, their file names and their metadata never leave your device.
Is image metadata removed?
Yes. Re-encoding through the browser canvas drops EXIF, GPS and other metadata from the compressed output.
How does quality affect JPG and WebP?
JPG and WebP use lossy compression: a lower quality setting makes a smaller file but discards more detail. Most photos look fine around 70–80%. The number is a quality setting, not a guaranteed size reduction.
Why might a PNG not get smaller?
PNG is lossless, so the quality slider doesn't apply and browser PNG re-encoding often can't beat the original. For big savings on a PNG, convert it to WebP or JPG in the Photo Editor.
Why can a compressed file occasionally become larger?
If an image is already optimized, re-encoding can add overhead and grow the file. The 'Keep the original if compression makes the file larger' option is on by default, so you never end up with a bigger file by accident.
What happens to transparency?
Transparency is preserved. Because the format is kept, transparent PNG and WebP images stay transparent.
What about animated WebP or GIF files?
GIF isn't supported here. Animated WebP is compressed as a single (first) frame, so animation is not preserved — keep the original if you need the animation.
Are there size limits?
Processing happens on your device, so very large files or huge batches are limited by your available memory. We recommend keeping files under about 30 MB each.
When should I choose WebP instead?
WebP is usually smaller than JPG or PNG at similar quality. This tool keeps your format; to convert to WebP, use the Photo Editor.
How do I avoid quality loss from re-compressing?
Each lossy re-encode of a JPG or WebP loses a little more detail. Compress once from the original image rather than repeatedly compressing an already-compressed file.
