How to compress images
- 01
Add your images
Select JPG, PNG or WebP files, one or a whole batch.
- 02
Set compression
Compression defaults to 80% quality. Keep the original format or switch to JPG, PNG or WebP, and optionally cap the dimensions.
- 03
Compress and download
Check the before-and-after size, then download each file or all of them as a ZIP.
Three ways to make an image smaller
- Lower the quality: applies to JPG and WebP output. 70–85% usually keeps photos looking good.
- Change the format: WebP is often smaller than JPG for the same visual quality, and far smaller than PNG for photos.
- Reduce the dimensions: a 4000 px phone photo capped at 1600 px has about a sixth of the pixels.
A note about PNG
PNG is lossless, so it has no quality setting. Re-saving a PNG as PNG may not make it smaller and can even make it larger. For PNG files, reduce the dimensions or switch the output to WebP or JPG. The result always shows whether a file became smaller or larger.

Frequently asked questions
How do I compress an image without losing visible quality?
Start at 80–85% quality with the original dimensions and compare. For photos, WebP at the same quality is usually smaller than JPG.
Can I compress an image to an exact size in KB?
Not directly. There is no target-size mode; lower the quality or the maximum dimensions until the reported output size fits your limit.
Why did my PNG not get smaller?
PNG output is lossless, so there is no quality to lower. Choose WebP or JPG as the output format, or reduce the image dimensions.
Are my images uploaded to compress them?
No. Compression uses your browser's own image encoder on this device. Images are not uploaded to WeDoConvert servers.
Is EXIF metadata removed when compressing?
Yes. Compressed images are re-encoded from their pixels, so EXIF data is not copied. To remove metadata without re-compressing, use Remove EXIF Data instead.
