Screenshot Compressor
Compress
The canvas previews the compressed result live as you adjust the settings. Click Compress for the exact size and a before/after split — drag the divider to judge the quality, then download. The original file is never modified.
Your images are processed locally in your browser and never uploaded to any server.
Screenshots are usually PNG files full of flat colors and text, which means they compress extremely well when you use the right format. This tool shrinks them for email attachment limits, chat uploads and ticket systems, and it tells you honestly when keeping PNG beats converting.
How to use the screenshot compressor
- Add your screenshots (up to 30 at once).
- Keep PNG for maximum text sharpness, or pick WebP for the best size-to-sharpness ratio.
- Compress and check the before/after preview on each file.
- Download individually or as one ZIP.
Frequently asked questions
Why do screenshots compress so well?
They are mostly flat background colors, repeated UI elements and text: very little of the image carries unique information. WebP typically cuts a screenshot by 50–70% with zero visible difference, and even re-encoded PNG (which stays lossless) often shrinks 10–30%.
Which format keeps text sharpest?
PNG and WebP both do, since both support lossless modes and clean edges. JPG is the one to avoid for screenshots: its compression smears sharp text edges visibly, especially on red and blue UI text.
How small should a screenshot be for email?
Under 1 MB keeps every mail provider happy and recipients on mobile connections happier. The target-size mode hits an exact ceiling automatically, stepping down quality before it ever touches resolution.
