Getting a PNG under 100 KB
PNG keeps every pixel exactly, which is why a single screenshot or scanned page saved as PNG can be several megabytes. To get it under 100 KB it has to be converted to JPEG, which is what almost every upload form accepts anyway.
We convert and then step pixel dimensions and JPEG quality down together, keeping the gentlest step that fits under 100,000 bytes. Transparent areas become white, since JPEG has no transparency.
Tips
- Need to keep transparency, for a logo on a colored background? Then the result must stay a PNG, and this tool is not the right fit.
- Crop screenshots to the part you need. A full-screen capture of a 4K display is a lot of pixels to squeeze.
- Check that the form accepts .jpg. Most that say 'image' do; a few insist on PNG.
How it works
- 1
Drop your file
A PDF or an image. It goes over an encrypted connection and nowhere else.
- 2
Pick your limit
Choose the size the form asks for. We start with a cleanup that changes nothing you can see.
- 3
Download it
If it needs more, we find the gentlest quality setting that still fits, and delete everything soon after.
Questions
Is it free?
Yes. There is no sign-up and no watermark.
What happens to my file?
It is processed on our server and deleted automatically: the original 5 minutes after the run finishes, the compressed file after 10. A file you upload but never compress is deleted within 30 minutes. You can also delete everything right away with Delete now.
Will it look worse?
We try a lossless cleanup first, which does not change how the file looks. Only if that is not enough do we lower image quality, and we pick the gentlest setting that still fits your size.
What if my file cannot get that small?
You get the smallest version we could make and a clear note saying so, instead of a file that silently misses the limit.
Why does the size page aim a little under its limit?
Some sites count a kilobyte as 1000 bytes and others as 1024. We aim under the stricter one, so a 200 KB page aims for 200,000 bytes and the file passes either way.
