Compress Image to 50KB

Getting a photo under 50KB

Add one or more photos, including HEIC photos from an iPhone. Each is saved as a JPG at the highest quality that fits in 50,000 bytes; if quality alone can't get there, the width and height are reduced in proportion. The result row shows the size in KB and exact bytes, the dimensions and the quality used, and Preview shows the original and the result side by side.

A photo that is already under 50 KB in the same format is left unchanged.

Dimensions that work at 50KB

At medium JPG quality (about 1–2 bits per pixel), a 4:3 photo at 50 KB comes out around 520–730 px on the longer side. That is enough for a sharp passport-style photo on screen and for most profile pictures. If you only need a small photo, set Max width: fewer pixels leave room for a higher quality, which often looks better than a larger image at lower quality.

For exact dimensions, such as 200 × 230 px, use the photo resizer in KB.

Forms that ask for 20-50KB

A range means both limits are checked. This page guarantees the maximum. A typical photo lands just under 50 KB, well above 20 KB, but a very simple or very small image can come out smaller than the minimum. If the result is under 20 KB and the form has a minimum, use the photo resizer in KB with Min file size set to 20: it keeps the quality high enough to stay inside the range. For a strict 20 KB cap, use compress image to 20KB.

Keeping faces sharp

• Crop before compressing so the face fills most of the frame; the bytes then go on the face, not the wall behind it.
• Take the photo in daylight. Noise from dim indoor photos is expensive to compress and turns blotchy.
• Start from the original photo each time. Every JPG save loses a little more detail, so compressing an already-compressed file twice gives a worse result than compressing the original once.
