How to compress image for form upload
Check the limit
Find the KB cap on your form (often 20, 50, 100 or 200KB).
Enter it
Type that number into the target field.
Upload the result
Download the resized image and attach it — it’ll fit first try.
About this tool
Online forms for exams, job applications, passports and visas almost always cap photo and document uploads at a specific size in KB. Photos straight from a phone are far too large, so uploads fail with a confusing error. Set the form’s exact limit here and the tool guarantees the output fits.
Everything is processed on your device, so sensitive documents and ID photos are never uploaded to anyone’s server.
Questions
How do I find my form’s size limit?
It’s usually written next to the upload button, e.g. “max 100KB”. Enter that number as the target.
What if there’s also a dimension limit?
Use the Resize tool first to set the pixel size, then compress to the KB target here.
Is my document uploaded anywhere?
No — all processing happens locally in your browser.
