Compress an image
Pick a quality level and see how much smaller each file gets before you download. Compression runs in your browser, so even confidential images stay on your device.
How to use the compress image tool
- 1
Add images
Drop JPG, PNG or WebP files, or click to choose them.
- 2
Choose a quality
Lower quality means smaller files. Around 70–85 is usually a good balance for photos.
- 3
Compare and download
Each file shows its old and new size. Keep the original if a file doesn’t get smaller.
Why PNGs are compressed as WebP or JPG
PNG is lossless, so a browser can’t make a PNG meaningfully smaller without changing its format. For PNG input you can choose WebP (keeps transparency) or JPG for the biggest savings.
Frequently asked questions
Are my files uploaded anywhere?+
No. This tool runs entirely in your browser, so the file never leaves your device. Closing the tab discards it.
What quality should I use?+
For photos, 70–85 usually looks the same as the original at a fraction of the size. For screenshots with text, stay above 85 or use WebP.
Why did a file get bigger?+
Images that are already heavily compressed can grow when saved again. The tool shows the new size so you can keep the original in that case.
Can I compress a PNG and keep it as PNG?+
Not meaningfully in a browser, because PNG is lossless. Converting to WebP keeps transparency and usually cuts the size substantially.
Is it free? Do I need an account?+
Yes, it’s free and there’s no signup, watermark or daily limit. An account is only needed if you want teammates or clients to comment on the file in edits.io.
Need feedback, not just a file?
Click anywhere on mockups, screenshots and artwork to leave precise comments. Clients comment with a link, no account needed.
