Why this matters
Online visa and passport portals routinely cap photo uploads at 20 KB, 30 KB, or 50 KB — a threshold that most smartphone cameras vastly exceed. The compressor binary-searches quality levels until your photo lands under the limit, letting you submit on the first attempt instead of guessing quality settings in another app.
Step by step
- 1Open the Image CompressorDrop in your passport or ID photo (JPG recommended).
- 2Set the target to 20 KBType "20" and choose "KB".
- 3CompressThe tool iterates in-browser to hit the target.
- 4Check the previewThe face should still be clear at 20 KB for most modern photos. If it looks too degraded, try a higher-resolution source image.
- 5Download and submitSave the compressed photo and upload it to the application portal.
Frequently asked questions
Why do government portals require photos under 20 KB?
Legacy upload systems with low server storage quotas set these caps years ago. The limits are rarely updated even as camera megapixel counts have increased.
Will the face still be recognizable at 20 KB?
Yes, for a correctly taken passport photo (tight face crop, even lighting, white background). A 1–2 MP crop of a face compresses well at 20 KB because skin and solid backgrounds are highly compressible.
Should I use JPG or PNG for a 20 KB photo?
JPG. PNG at 20 KB would be extremely degraded because PNG is lossless and far less efficient for photos at tiny file sizes.
Is my passport photo uploaded anywhere?
No. Compression runs entirely in your browser. Your photo never leaves your device, which is especially important for identity documents.
What if the portal also requires specific pixel dimensions?
Resize first using the Image Resizer (e.g., 600×600 px), then compress to 20 KB here.
My country's portal asks for under 50 KB or 30 KB — will this work?
Yes. Set the target to whatever value your portal specifies — 30, 50, or 100 KB.
