50 KB is a demanding limit that requires balancing quality and dimensions. This tool does that math for you — it tries multiple qualities and, when needed, scales the pixel size down proportionally until the file is guaranteed to fit.
Tip: if the image is a screenshot with text, crop it to the relevant area first with the crop tool, then compress: you will get far more sharpness out of the same kilobytes.
How it works
- 1
Drop your images: the target is already set to 50 KB.
- 2
Quality (and dimensions, if needed) are tuned automatically.
- 3
Check the final size on each card and download.
Frequently asked questions
What resolution fits in 50 KB?
As a reference, a JPG photo of about 800×600 px at medium-high quality. The tool automatically finds the exact balance for each image.
Can I compress several images to 50 KB at once?
Yes: the target applies to the whole batch and every card shows the final size achieved, with individual or ZIP download.
Are my images uploaded to a server?
No. All processing happens inside your browser using the Canvas API: your files never leave your device, there are no upload queues, and the tool even works offline once the page has loaded.
