PNG is a lossless format: every pixel is preserved exactly, which is wonderful for crispness and terrible for file size. A photographic PNG can easily weigh ten times more than the same image saved as JPG, because lossless compression can't discard the fine detail cameras capture.
There's a second culprit: the alpha channel. Transparency data adds weight to every PNG, even ones that don't visibly use it. Between losslessness and transparency, PNGs start heavy and stay heavy — which is why they need deliberate compression.
The PNG you'll most often need to shrink is a screenshot. A retina screenshot of a full screen can weigh 2–4MB — fine on your disk, painful as an email attachment or a documentation upload.
Screenshots compress better than photos because flat colors and repeated patterns are PNG's home turf, but “better” still isn't small. This page's manual quality control lets you dial a screenshot down until the text stays razor-sharp and the file stops being embarrassing.
Logos, icons, UI elements, watermarks: anything that needs to float over a background needs PNG's alpha channel. JPG can't do transparency at all — converting a transparent PNG to JPG fills the transparent areas with a solid color, usually white or black.
So the rule is simple: if the image relies on transparency, it stays a PNG and you compress within the format. Only flatten to JPG when the image is fully opaque and photographic — that's where the dramatic 10x savings live.
The biggest PNG wins aren't compression — they're format changes. A photo accidentally saved as PNG (common with phone screenshots of photos, or exports from design tools) will shrink 80–90% the moment it's re-encoded as JPG, with no visible difference.
Judge by content, not extension: photographic content with no transparency belongs in JPG; crisp graphics, text, and anything transparent belongs in PNG. Our 100KB compressor page is the natural next step when a photo needs to hit a hard size limit.
Because PNG compression here stays within the format, your graphics survive intact — but good habits still apply. Keep the original PNG as your master, and treat compressed copies as delivery files for the web, email, or docs.
And as with everything on this site, the work happens in your browser. Screenshots often contain sensitive information — chats, dashboards, unreleased work — and none of it is uploaded anywhere during compression.
No — as long as the file stays a PNG, the alpha channel is preserved. Transparency is only lost if you convert the image to JPG, which doesn't support it. Keep transparent graphics in PNG and compress within the format.
Retina displays pack four times the pixels of older screens, and PNG stores every one losslessly. Screenshots of busy screens with lots of detail compress poorly. Dial the quality down on this page until text stays sharp — that's your sweet spot.
If it's a photo with no transparency, almost certainly yes: expect 80–90% smaller files with no visible difference. If it has transparency or razor-sharp text and lines, keep it as PNG.
Yes — batch as many as you like; each is compressed independently and you can download them one by one or as a ZIP, with no limits.
