How to compress a PNG to 100 KB
- Drop your PNG into the box above or click Select files. The target is already set to 100 KB.
- The tool lowers quality step by step until the file is at or below 100 KB. If that still isn’t enough, it scales the image down a little and tells you the new dimensions.
- Check the result with the before/after slider, then press Download.
Need 50 KB, 200 KB or another size?
After adding a file, open Compression settings › Advanced options and type any value in Target size (KB). Common limits:
- 20–50 KB: government and exam portals, signature and photo uploads
- 100 KB: job portals, ID photos, forum avatars
- 200–500 KB: marketplaces, website hero images, email newsletters
Tips for hitting a small target
- Resize first. A 4000 px screenshot will never look good at 50 KB. Set a maximum width such as 1200 px under Resize images.
- Fewer colors for flat graphics. Logos and icons often look identical with 32–64 colors.
- Turn dithering down for flat logos. Keep it on for gradients.
- Photos? PNG is the wrong format for large photos. If the portal accepts JPG, a photo will fit 100 KB far more easily. See PNG vs JPG vs WebP.
Private by design
Size limits usually come with sensitive uploads: ID photos, signatures, certificates. This tool compresses on your own device and never uploads the image, so nobody else ever sees it. Transparency is kept too.
