Compress Image to KB
When filling out online forms or applications, there is often a specific file size limit for photos or attachments; this requires you to convert your photos to the appropriate size (in KB), though you can also use settings that automatically format Photo to 20KB, Photo to 50KB or Photo to 100KB the file to the required size beforehand:
- Compress image to 20kb — the tightest limit, usually for small ID-photo slots on older government portals; expect some visible quality loss on large source photos.
- Compress image to 40kb — a common signature or thumbnail-photo requirement on exam and recruitment forms.
- Compress image to 50kb — the most requested passport-photo size for exams like SSC, UPSC, banking and university admissions.
- Compress image to 100kb — the standard cap for Aadhaar updates, PAN corrections and most Indian e-forms, with good visible quality.
- Compress image to 200kb — comfortable for resume photos, LinkedIn-style profile pictures and job-portal uploads.
- Compress image to 300kb — a good fit for email attachments and application forms that reject files over a few hundred KB.
- Compress image to 400kb — a generous ceiling for high-resolution uploads like portfolios or blog images.

Photo Compress FAQ
How much can I compress an image without losing visible quality?
It depends on the photo, but reducing quality to around 70-85% usually keeps images looking sharp while cutting file size noticeably.
Can I compress an image to an exact size, like 100 KB?
Yes — switch to "Compress to Size" and enter your target size in KB; the tool adjusts quality automatically to get as close as possible.
Which format gives the smallest file size?
JPEG generally compresses photos smaller than PNG. Use our Convert Image tool if you also need to change the format.
Is compression done on a server?
No, all compression happens locally in your browser using the Canvas API — your file is never uploaded.
How do I compress an image to 20kb or 50kb for a form?
Upload your photo, switch to "Compress to Size" and enter 20 or 50 — or open the ready-made Compress Image to 20KB or Compress Image to 50KB page. The tool automatically finds the quality level that fits the limit — common for exam and passport-photo uploads.
What KB size do government forms like Aadhaar or PAN usually need?
Most Indian government portals ask for photos or signatures around 20 KB to 100 KB, and scanned documents up to 200-300 KB. Check the exact limit on your specific form before uploading.
