Government & Portal Upload Requirements Cheat Sheet

Online submission forms have strict image limitations. If your upload fails, consult this reference guide to find the exact threshold your photo must satisfy:

3 Ways to Reduce Image Size Without Losing Quality

1. Perceptual JPEG Quality

Standard JPEG compression between 75% and 85% removes invisible high-frequency chrominance data that the human eye cannot discern. This shrinks file weight by 60% with zero perceptual loss.

2. Convert to WebP Format

WebP uses modern VP8 keyframe predictive encoding, delivering files 30% smaller than JPEG at equivalent visual quality. Most modern web forms accept WebP.

3. Stitch ID Cards onto Single PDF

If you are uploading front and back ID cards or driving licenses, use our ID Card Stitcher to combine both sides into a crisp, print-ready document under 1MB.

Frequently Asked Questions

Why are iPhone HEIC photos rejected by online upload forms?

Modern iPhones capture photos at 24 megapixels or 48 megapixels. Even with HEIC compression, high-resolution textures create files between 2 MB and 5 MB. Most government, banking, and university portals impose strict upload limits (often 200 KB, 500 KB, or 1 MB) and reject the uncompressed HEIC file extension.

What settings should I use to compress an image under 200KB for visa/passport portals?

Select JPG or WebP as the output format, set the Quality slider to approximately 65-75%, and optionally reduce the resolution scale to 50% or 600x600 pixels (the standard for US visa / DV lottery applications). This yields a crisp photo well under 200 KB.

Does compressing an image to under 1MB ruin the clarity or text on an ID card?

No. High-quality WebAssembly bicubic scaling and modern DCT encoders preserve sharp text and facial features even when compressed to 300KB-600KB, which easily satisfies the 1MB ceiling.

Can I batch-compress multiple HEIC photos at the same time?

Yes. Our converter allows you to select or drop dozens of HEIC photos at once. Each photo is compressed multi-threaded in parallel using WebAssembly in your browser.

Is it safe to compress confidential passport and tax document photos here?

100% yes. Unlike typical online compression tools that transmit your files to cloud servers, our conversion and compression engine executes entirely within your browser's local sandbox memory. No file or image data ever leaves your device.
