Compress image to 50 KB
Aim for a file no larger than 50,000 bytes. Start with quality adjustment, then allow smaller dimensions if your image needs more compression.

How to fit an image within 50 KB
- Choose the photo or image required by your upload form.
- Keep the 50 KB maximum, select JPG or WebP, and decide whether smaller dimensions are acceptable.
- Compress, inspect the actual size and legibility, then download only after the target is reached.
Example
A large photo for a small upload field → a JPG no larger than 50,000 bytes. Its final dimensions depend on the source; check them in the result.
When to use this tool
Use this when a form explicitly limits an image to 50 KB. If the form also specifies minimum pixel dimensions, turn off automatic downsizing and check both requirements before uploading.
Supported formats & limits
One static image at a time, up to 20 MiB and 24 megapixels. Lower device limits are shown in the workspace. JPG, PNG, WebP, AVIF and HEIC/HEIF inputs are supported where the local decoder is available. Output is JPG or WebP. KB means 1,000 bytes. EXIF/GPS metadata is removed; animated images are unsupported.
Something isn’t working ↗Good to know
Will the file be exactly 50 KB?
No. 50 KB is a maximum of 50,000 bytes. A smaller valid file is kept smaller; the tool never adds padding to reach an exact size.
Can a detailed photo stay sharp at 50 KB?
Not always. The tool tests lossy quality settings, then reduces dimensions if you permit it. Inspect faces and text before using the output. Choose a higher limit if the result loses too much detail.
What if I must keep the original dimensions?
Turn off Allow dimensions to shrink. If quality changes alone cannot reach the budget, the tool reports that the target was not reached and offers no oversized download.
Which format should I use for a form?
Follow the form’s accepted formats. JPG is widely accepted for photos but cannot keep transparency. WebP can keep transparency, but some forms do not accept it.
