Compress PNG to 100 KB
Reduce your png to 100 KB or less while preserving the best possible quality. This tool is built for resumes, profile photos, web forms and most online applications that cap uploads around 100 KB. Everything runs in your browser, so nothing is uploaded to a server.

Supports .png · Max 20 MB per file
Upload up to 10 files at once — they'll be compressed together and packed into one ZIP to download.
How to use this tool
Drag your png into the upload area (or tap to browse on mobile), confirm the target of 100 KB, then press Compress. The tool analyzes the image, iteratively adjusts quality and, if needed, dimensions, and stops as soon as the output is at or below 100 KB. Download the result or compress another file — no account or upload required.
Getting a png down to 100 KB
Most everyday photos reach this size with only mild, hard-to-notice softening. It is a practical middle ground between file size and visual quality for general use. The compressor always tries quality reduction first and only resizes the image's dimensions if quality adjustment alone cannot reach 100 KB, so you keep the original resolution whenever possible.
Why you might need this
Many forms, portals and application systems enforce a hard file size ceiling rather than a quality standard. A photo straight from a modern phone camera is usually several megabytes — far above limits like 100 KB — so it needs deliberate compression, not just resizing, to be accepted.
Tips for the best result
- Start from the highest-quality original you have — compressing an already-compressed file compounds quality loss.
- Crop out unnecessary background before compressing; a tighter crop means more of your size budget goes to the subject that matters.
- Keep the original file until you are happy with the compressed version, in case you want to try a different target size.
Frequently Asked Questions
How can I reduce a png to 100 KB?+
Upload your file above, keep the target set to 100 KB, and press Compress. The tool automatically finds the highest quality setting that still fits within 100 KB.
Will compressing reduce quality?+
Yes — fitting a file into a smaller size always involves some trade-off. This tool prioritizes staying at or under 100 KB while keeping quality as high as that budget allows; it will not falsely claim zero quality loss.
Are my files uploaded to a server?+
No. Image compression on this page runs entirely in your browser using the Canvas API. Your file never leaves your device.
Can I use this on my phone?+
Yes. The uploader supports the mobile file picker and camera roll, and the interface is designed to work on small screens.
What happens if the target size is impossible to reach?+
If 100 KB cannot be reached without extreme degradation, the tool clearly warns you and gives you the smallest reasonable version it could produce instead of silently failing.
Will my PNG's transparency be preserved?+
Yes. As long as the tool keeps the PNG format, transparent areas stay transparent. If quality-only compression cannot reach your target, dimensions are reduced before transparency is ever sacrificed.
