Handy tips
- For photos (JPG), even 70–80% quality usually cuts the size a lot with barely any visible difference.
- For simple graphics like logos or icons, saving as WebP is lighter than PNG at the same quality.
- If it’s for the web, resize the width first and then compress to drop the size even further.
Lossy vs. lossless compression: what's the difference
Image compression comes in two flavors. Lossy compression shrinks the file a lot by discarding color and detail information your eye can barely notice — JPG and WebP are the usual examples. Lossless compression throws none of the pixel data away and just stores it more efficiently, so the savings are smaller but the original is preserved perfectly. PNG belongs in this camp.
The quality slider in this tool controls the strength of lossy compression. The lower you go, the more information is dropped and the smaller the file gets, but push it too far and edges can smear or blocky patterns can appear. That's why it's safest to lower it while checking the result preview with your own eyes.
What quality percentage is right — a practical guide
For photos, 75–85% quality is the sweet spot. In that range it's almost impossible to tell apart from the original on screen, yet the size often drops to less than half. Pick 60–70% when speed matters more than quality, like sending in chat or sharing something temporary, and 90% or higher when detail counts, such as portfolios or print.
Even at the same quality value, results vary by image content. Photos with lots of smooth areas — sky or a solid background — hold up well even at lower quality, while photos full of fine texture like grass or hair look better if you nudge the quality a bit higher.
What will you use it for — recommended settings by purpose
For posting on a blog or website, the most efficient combo is to first shrink the width to its on-screen display size (usually 1200–1600px) and then compress at around 80% quality. Pages load noticeably faster, and it helps the performance score search engines look at.
When there's a size limit, like an email attachment or a website form upload, watch the size figure on the result card and step the quality down until it comes in under the limit. For online-store product photos, color matters, so 85% or higher is a good bet.
Frequently asked questions
You control it with the slider. Around 80% is usually hard to tell apart by eye while often cutting the size to less than half. Compare in the preview and pick the point you like.
No, your original stays as is. You just download a new compressed copy, so there’s nothing to worry about. And since everything runs in your browser, the original never leaves your device.
You can upload JPG, PNG, and WebP, and the result is saved in the same format.
For now it handles one at a time. For multiple images, save one and then upload the next, repeating the same steps.
Lossy compression drops a little information every time you save. Re-compressing an already compressed file stacks up the quality loss, so it's best to always start from the original file and hit your target size in one pass.
It depends on the starting file. A high-quality JPG straight from a camera or phone usually shrinks by around 50–80% at 80% quality. An image that's already heavily compressed may shrink far less. You can see the exact reduction on the result card.
