How to use
- Add images. Drop one or many files on the box above. Each gets its own row with the original size and dimensions.
- Pick a target. Click a preset chip (10 KB to 500 KB) or type any custom size in kilobytes.
- Compress and download. The tool searches for the best JPG quality that fits under the target, and only shrinks dimensions if it has to. Compare before and after, then download each file or all at once.
FAQ
How does it hit an exact size like 50 KB?
It does a binary search over JPEG quality (0.05–0.95), encoding the image up to eight times to find the highest quality that lands under your target. If even the lowest quality is still too large, it reduces the dimensions by 10% and searches again, repeating until the file fits.
Why did my image get smaller in pixels?
Very small targets (10–20 KB) cannot hold a large photo at any quality, so the only way to fit is to reduce the resolution. The row shows the final width × height so you know what you're getting. Choose a bigger target if you need to keep dimensions.
Can I keep the PNG format?
Yes — tick "Keep PNG as PNG". PNG is lossless so there is no quality setting; the tool only downscales until the file fits. For photos, converting to JPG is far more effective. Transparency in PNGs converted to JPG is filled with white.
Is this good enough for passport photo and job application uploads?
Yes. Those portals usually demand "under 100 KB" or "20–50 KB" with a minimum pixel size. Set the target here, check the reported dimensions meet the portal's minimum, and download.
