‘Photo size must be less than 50 KB.’ If you’ve applied for a job, admission or government scheme online, you’ve probably seen this message. A normal phone photo is 2–5 MB – that’s 50 to 100 times too big. Here’s how to fix it in seconds.
How to compress a photo to a specific KB
- Open Compress Photo to KB.
- Upload your photo.
- Pick a preset (20, 50, 100 or 200 KB) or type the exact limit.
- The tool automatically reduces dimensions and quality until the file fits.
- Check the final size and preview, then download.
Get a clearer result at small sizes
- Crop first to your head and shoulders with Crop Image; less background means more detail on your face.
- Use a plain background; busy backgrounds use up file size.
- Match the pixel size if the form specifies one, e.g. 200×230 px, using Resize Image.
Signature uploads too
Many forms also want a signature under 20–30 KB. Create a clean one with Signature Maker, then compress it here.
FAQ
Why is my file still slightly over the limit?
Some forms count 1 KB as 1,000 bytes and others as 1,024. Aim a little below the limit, e.g. 45 KB for a 50 KB limit.
JPG or PNG?
Use JPG for photos; it is far smaller than PNG at the same size.
Conclusion
Crop, set the KB limit and download. Your photo will upload first time.
