How to use this tool
- Select your file, drag it onto the box above, or paste it from your clipboard.
- Processing starts automatically — there is nothing to configure.
- Check the result panel, which shows the original size, the final size and the output dimensions.
- Click Download to save it.
PNG is lossless, which means it ignores quality settings entirely. The only way to shrink a PNG is to reduce its pixel dimensions or its colour count — so this tool scales the image down in steps until it fits. If your image is a photograph rather than a graphic, converting to JPEG will produce a far smaller file at the same visual quality.
The specification
| Target file size | Under 200 KB |
|---|---|
| Output format | PNG |
| Method | Dimension reduction — PNG is lossless and ignores quality settings |
| Transparency | Preserved |
Why uploads get rejected
Meeting the size is only part of it. These are the failures that actually come up:
- The image is a photograph saved as PNG. PNG cannot compress photographic detail well — a JPEG of the same image is often five times smaller.
- You needed transparency but the target size is very small. Transparency forces PNG, which limits how far the file can shrink at a given size.
- The dimensions had to drop a long way to reach 200 KB. Check the result is still usable.
How it works
Most compressors pick a fixed quality level and hope for the best, which is why they either overshoot the limit or land far below it and throw away detail you did not need to lose.
This tool runs a binary search instead. It encodes your image at a mid-range quality, measures the resulting file, then narrows the range — higher if there is room, lower if it is over — repeating seven times. It keeps the largest result that still fits. If the lowest quality is still too big, it reduces the pixel dimensions and searches again.
All of it runs on your own device using the browser's canvas API. Nothing is transmitted.
Who uses this
Situations where the output format is fixed — a form that accepts only PNG, or a workflow where the format must not change.
Frequently asked questions
Why keep PNG rather than convert?
PNG preserves transparency and stays lossless, which matters for logos, screenshots and graphics with sharp edges. If your image is a photograph and you do not need transparency, JPEG is a better choice.
Why does quality not affect PNG size?
PNG compression is lossless — it reconstructs the image exactly, so there is no quality dial to turn. Size is determined by dimensions and colour complexity, which is why this tool scales the image instead.
Will the quality drop?
Some quality is always lost when a file gets smaller — that is what compression means. The tool searches for the highest quality that still fits under your limit, so it gives up as little as possible.
Are my files uploaded to a server?
No. Everything runs inside your browser on your own device. Your file is never transmitted and never stored by us. You can confirm this by opening your browser’s Network tab while you use the tool — you will see no upload request.
Is there a limit on how many files I can process?
No. There is no daily cap, no account, and no watermark. Because the work happens on your device rather than our servers, there is nothing for us to ration.
Is this tool really free?
Yes — no account, no trial, no watermark, and no cap on usage. It runs on your own device rather than our servers, so there is no cost for us to pass on.
Does it work on mobile?
Yes. The interface adapts to phone and tablet screens, and everything runs in the browser, so there is no app to install.
