How to compress a photo to under 50 KB (without wrecking it)
A step-by-step guide to shrinking a JPG or PNG to under 50 KB for exam and government forms — and why quality doesn’t have to suffer.
Most exam and government forms cap the photo at 20 KB, 50 KB, or 100 KB. A photo straight from a phone is 2–5 MB — that’s 40 to 100 times too big. Here’s how to get it under the limit and still have it look sharp.
Why your photo is so large
Two things bloat a photo: resolution (the number of pixels) and quality (how much detail the JPG keeps). A form photo only needs to be a few hundred pixels wide. Shrinking the resolution first does most of the work — then a small quality reduction finishes the job.
The reliable way to hit a target size
- 1Resize the photo to the dimensions the form asks for (often around 200×230 pixels). This alone can cut the file to a fraction of its size.
- 2Save as JPG, not PNG — photos compress far smaller as JPG.
- 3Lower the quality in small steps and watch the file size. Stop the moment you’re under the limit.
- 4Zoom in to check the face is still clear before you upload.
Don’t compress the full-resolution image straight to 50 KB — you’ll get a blurry mess. Resize first, compress second. Order matters.
The fast way
Instead of exporting, checking, and re-exporting, UploadEze lets you set a target size (say 50 KB) and it finds the right settings in one pass — right on the form you’re filling, without uploading your photo anywhere.
