Compress Image for Exam Form
Fit the photo and signature limits on any exam or government form — free, private, nothing uploaded.
Filling in an online exam or government application always seems to trip on the same step: the photo and signature upload. The portal demands a specific format and a strict file-size limit, and your camera photo is many times too large. This page is built for exactly that hurdle — compress your photo or signature to whatever KB limit the form asks for, right here, without installing anything or handing your documents to a random website.
Keep the format on JPG (what almost every portal expects), then use the quality and max-width controls to land on your target — 20 KB, 50 KB, 100 KB or anything in between. The live size readout does the guiding, and because everything runs in your browser, your photo and signature never leave your device.
Read the form’s limits
Note the required format (usually JPG) and the size caps — photos are often 20–100 KB and signatures 10–20 KB.
Drop your file
Add the photo or the scanned signature. Do one at a time so you can hit each limit precisely.
Dial in the target
Lower the quality and, for tight limits, the max width, until the live size matches what the form asks for.
Download and upload
Save the compressed file and upload it to the portal. Repeat for the second file if needed.

Typical photo and signature requirements
Although every exam board words it differently, the requirements follow a familiar pattern. Reading them carefully before you compress saves a lot of rejected uploads:
- Photo — usually a recent passport-style colour photo, JPG format, often between 20 KB and 100 KB.
- Signature — your signature on white paper, scanned or photographed, JPG, commonly 10 KB to 20 KB.
- Dimensions — some forms also specify pixels (for example around 200×230 for a photo); set the max width to match if so.
- Background — a plain, light background is expected for the photo, and a clean white one for the signature.
Compressing the photo and signature separately
The photo and the signature almost always have different limits, so handle them one at a time. For the photo, a mid quality and a width around 600–800px will reach the 20–100 KB range typical of these forms. Aim for the upper end of whatever the form allows, because a clearer photo is checked against your face at the test centre.
The signature is easier: it is mostly white with thin strokes, so it compresses to 10–20 KB effortlessly. Keep JPG, set a small max width (300–400px), and lower the quality until it fits. If your scan has a grey or off-white background, that is usually fine — JPG output sits on white, which is what forms expect.
Why compress your documents on your own device
Your exam photo and signature are personal identity documents, and many popular "resize for form" websites upload them to a server to do the work. That means your face and signature sit on someone else’s computer, and you have no idea how long they are kept or who can see them.
This tool never uploads anything. The compression is performed by your browser using the Canvas API, and the finished file is handed straight back to you as a download. Nothing is transmitted, nothing is stored, and there is no sign-up — the safest way to prepare identity documents for an official portal.
Related tools & guides
How do I compress a photo to 20 KB or 50 KB for a form?
Keep the format on JPG and lower the quality slider until the live size reaches your target. For tight limits like 20 KB, also reduce the max width. Do the photo and signature separately.
Which format should I use for exam forms?
Almost all exam and government portals accept JPG/JPEG. This tool outputs JPG by default, which also gives the smallest size for photos.
Can I compress a signature image too?
Yes. Signatures compress very easily — set a small max width (300–400px) and lower the quality until the size fits the form’s limit, often 10–20 KB.
What if the form also specifies pixel dimensions?
Set the max width to match the pixels the form asks for (for example 200px), then adjust quality to meet the KB limit as well.
My upload keeps getting rejected — what’s wrong?
Check three things: the format is JPG, the file is under the size cap, and the dimensions (if specified) match. Compress the photo and signature to their own separate limits.
Is my document uploaded anywhere?
No. Compression happens entirely in your browser — your photo or signature never leaves your device. Free, no sign-up.
