How it works
Drop your image
Any common format, any size, even a whole batch. Nothing is uploaded — your browser reads the file directly from disk.
Quality is searched, not guessed
A binary search over JPEG quality finds the highest quality that fits under 50 KB. Dimensions are only reduced if the target is otherwise impossible.
Download a file that qualifies
A clean .jpg, guaranteed under the limit, with metadata stripped as a bonus. The card shows the exact size, dimensions, and quality used.
Why exactly 50 KB?
JPEG quality settings are a guessing game — 80% might give you 240 KB, 60% might give you 90 KB, and the form wants 50. This tool removes the guesswork: it binary-searches the JPEG encoder for the highest quality that lands under 50 KB, in eight precise steps, all on your device.
Tip for best results
PNG screenshots are accepted too — they're converted to JPEG automatically, since PNG can't reliably hit small targets.
Why trust ClientSide
- Compression runs entirely in your browser tab
- Files are read into RAM — never written to a server
- No network requests are made for your photos
- No file size limits, no daily quota, no watermark
- Metadata (GPS, camera info) is removed automatically
Frequently asked questions
How does this compress an image to exactly 50 KB?
A binary search over JPEG quality runs in your browser: encode, check the size, narrow the range — eight times. The result is the highest quality that fits under 50 KB. If even the lowest quality is too big, dimensions are stepped down and the search repeats.
Why can't I just save my JPEG at lower quality myself?
You can — but quality sliders don't map to file sizes, so it takes repeated exporting and checking. The binary search here does those iterations automatically and returns the best one.
Is my photo uploaded to a server?
No. The image is read and compressed by JavaScript in your browser tab. Nothing is sent anywhere — the compressed file is written straight from memory to your downloads.
What format is the output?
Always JPEG (.jpg) — the format forms expect, and the only common format that can be tuned to an exact size. PNG, WebP, BMP, and GIF inputs are converted automatically; transparency is flattened to white.
What if 50 KB is impossible for my image?
The tool reduces dimensions step by step until the target is reachable and labels the result. In practice any photo can be brought under 50 KB — very small targets simply produce smaller images.
Need more control over the image?
Our image editor can crop, resize to exact pixel dimensions, and adjust the photo before you compress it here. For removing hidden GPS/EXIF data without recompressing, use the metadata remover.
