PicPress Image Compressor

PicPress Image Compressor is a free online tool that makes JPG, PNG and WebP files smaller in your browser. You can compress many images at once, choose an encoder quality or a target size in KB, limit the longest edge, compare before and after, and download single files or a ZIP.

What it does

Batch compression of JPG, PNG and WebP
Quality mode or target-size mode (1 to 10,240 KB)
Optional output format and longest-edge limit (up to 8192 px)
Automatic mode keeps whichever is smaller: the new file or your original
Side-by-side comparison with real file sizes
Download one by one or as a ZIP

How to use it

Step 1

Upload or drag in one or more JPG, PNG or WebP images.
Step 2

Choose quality mode or target-size mode, then set the output format and longest edge if needed.
Step 3

Start compressing, compare the results and their sizes, and download single files or a ZIP.

Limits and notes

Up to 50 images per batch, 50 MB per file and 200 MB in total.
PNG at the original size is optimised losslessly, so the quality slider does not affect PNG.
JPG does not support transparency; transparent areas are filled.
Very small size targets may be impossible without reducing dimensions; unmet targets are flagged.

Privacy

Images are compressed locally in your browser and are not uploaded to any server.

Questions

Why did my image barely shrink?

It was probably already well compressed. At the same dimensions, automatic mode keeps the smaller original instead of re-encoding it larger. Lower the quality or the longest edge to go further.
