Compress an image to 50 KB

Fifty kilobytes is one of the most common limits on application forms, especially for passport-style photos. The target is already set to 50 KB: drop the photo and the tool returns the sharpest version that fits.

How to compress an image to 50 KB

Crop the photo to head and shoulders, the way the form asks.
Drop it here. The target is already set to 50 KB.
Keep JPG and, if the form gives dimensions, set the max width to match.
Run it and download the result.

Where the 50 KB limit comes from

Fifty kilobytes is the classic limit for passport-style photos on online applications: job and exam registrations, student portals, membership cards and many official forms. It dates from when servers and connections were slower, and it has stuck. The good news is that a face photo, cropped the way these forms want, fits comfortably in 50 KB at good quality.

Getting a photo that passes

Take the photo against a plain, light background, facing the camera, in even light.
Crop to head and shoulders with the crop tool. Most forms want the face to fill a large part of the frame.
If the form gives pixel dimensions, resize to match them exactly.
Compress here. The target is already set to 50 KB.

Why photos fail the upload even under 50 KB

Size is usually one rule of several. Forms also commonly check:

File type. Almost always JPG. This tool outputs .jpg by default.
Dimensions. For example 200 by 230 or 350 by 450 pixels. Resize before compressing.
Minimum size. Some forms reject files below 10 or 20 KB as too low quality. The tool aims just under your limit, not far below it, so this is rarely a problem.
Background and framing. Checked by people, not software, but a reason for rejection all the same.

iPhone photos

Photos from an iPhone are often HEIC, which most forms reject outright. Drop them here as they are: the tool converts and compresses in one step, and the result is a standard JPG. Your photo never leaves your device, which is worth something when it is a picture of your face going onto an official form.

Frequently asked questions

Are my photos uploaded?

No. Decoding and compression happen in your browser, on your own device. The photos never leave it, which matters for ID photos and personal pictures.

Is 50 KB enough for a clear face photo?

Yes. A head-and-shoulders photo around 350 to 600 pixels wide looks sharp at 50 KB. Problems only appear when a full-size phone photo is squeezed without cropping.

My photo is from an iPhone. Will it work?

Yes. HEIC photos are converted automatically, and the result is a JPG.

The portal still rejects the photo. Why?

Check the other rules on the form: many also require specific pixel dimensions, a plain background or a JPG file extension. The size is only one of the checks.
