Where a 500 KB limit is used
A 500 KB limit is most often used for full document scans, resumes and PDFs. A 500 KB cap is generous — it suits full-page document scans, resumes and combined PDFs. Forms that accept richer attachments often use a 500 KB ceiling.
Tip for hitting 500 KB cleanly
At 500 KB you have plenty of headroom; scan at a higher resolution for maximum legibility and just confirm the final file lands under 500 KB.
⚠️ File-size rules vary between forms and change between exam cycles — always confirm the exact limit in the official notification before you upload.
Frequently asked questions
Do I even need to compress for a 500 KB limit?
Often a phone photo or scan already exceeds 500 KB, so a light compression brings it under the cap while keeping excellent quality.
How do I compress an image to 500 KB?
Upload your photo above — the target is already set to 500 KB. Click Compress and the tool lowers the quality just enough to bring the file at or under 500 KB, then lets you download it. Nothing is uploaded to a server.
Will the image still be clear at 500 KB?
The tool keeps the highest quality possible while meeting the 500 KB limit. For full document scans, resumes and PDFs, 500 KB is enough to stay clear; very small targets naturally soften the image more.
Is it free and private?
Yes — completely free, no signup, no watermark, and the compression runs entirely in your browser so your file never leaves your device.
Need a different size?
Compress to any KB target, or resize to exact dimensions.
