Compress Image to 50 KB

Pictures that are compressed lose their hidden camera data, such as the GPS location. In an exact size, quality is lowered first, and the picture is made smaller only if it still does not fit.

Done on your device. Your pictures are never sent to FileXL.

How do I compress an image to 50 KB?

Add your picture to the box. The setting Under 50 KB is already selected, so the tool lowers the quality step by step until the file is 50 KB or smaller, and makes the picture a little smaller in pixels only if it still does not fit. Check the result in the before and after view, then download it.

How it works

How to compress an image to 50 KB in 3 steps

No app, no account and no waiting. The picture is compressed in your browser, so you see the new size straight away.

Add your picture

Drop a JPG, PNG or WebP file in the box, choose it from your device, or paste it. You can add several.
Check the size

The setting is already Under 50 KB. Change the number if your form wants a different size. A note shows if the picture had to be made smaller in pixels.
Download

Compare the picture with the original, then download it. The file is 50 KB or smaller.

Tips

Tips for a 50 KB picture

Use a plain background and good light. Clean pictures compress to a smaller file at a better look.
Crop to the face and shoulders first. Less area means a smaller file.
If the form wants exact pixels, such as 200 x 230, set them first with the Photo Resizer, then compress here.
Do not rename a PNG to .jpg. Use the Save as option to change the format properly.

Other ways to compress an image

Privacy

Private by design: your pictures never leave your device

Most online compressors upload your pictures to a server. This one does not. The work is done by your own browser, so an ID photo, a signature or a private picture is never sent to FileXL or anyone else. Turn off your internet after the page has loaded and it still works.

Need to send big files? Upload them with FileXL and share a link. Other tools that work the same way: the Photo Resizer, the PDF compressor and the QR code generator.

FAQ

Compress to 50 KB questions, answered

How do I reduce an image to 50 KB?

Add the picture. The tool is already set to Under 50 KB. It lowers the quality until the file fits, and makes the picture a little smaller in pixels if quality alone is not enough. Then download it.

Will my picture still look good at 50 KB?

A face photo of passport size usually looks fine at 50 KB. Use the before and after view to check, and try a different size if you are not happy.

The file is smaller than 50 KB. Is that a problem?

No. 50 KB is a limit. Upload forms reject files over the limit, and accept files under it. The tool keeps the best quality that still fits.

Are my pictures uploaded to a server?

No. The pictures are compressed in your browser, on your own device. They are never sent to FileXL or anyone else, and nothing is saved. Close the page and they are gone.

Does compressing an image reduce its quality?

JPG, WebP and the PNG palette method are lossy, so some detail is always lost. At a moderate setting, such as quality 75, the change is hard to see on most photos and the file is much smaller. At very small sizes the loss shows. Use the before and after view to check, and keep your original.

Which image formats can I compress?

JPG, PNG, WebP, GIF and BMP. GIF and BMP are saved as a new JPG or PNG. An animated GIF becomes a single still picture. Your browser may also open AVIF or HEIC pictures if it supports them, and the result is saved as JPG or PNG.

Can I compress many images at once?

Yes. Add up to 100 pictures, up to 100 MB each. The same setting is applied to all of them, and you can download them one by one or as a single ZIP file.

Is the photo location (EXIF data) removed?

Yes, for every picture that is compressed. It is written fresh, so hidden camera data such as the GPS location, the date and the phone model is not copied over. The picture still turns the right way up, because the tool applies its rotation before saving. One exception: a picture that is already under your size limit, or that cannot be made smaller, is returned as it is, with its hidden data. A note on its row tells you.

Can I compress an already compressed image again?

You can, but each lossy pass removes a little more detail. It is better to start from the original and pick the setting you want once.

Is this image compressor really free?

Yes. You can compress as many pictures as you like without paying, without an account and without a watermark. The files you download are yours to use for personal or business purposes. A small advertisement on the page helps to cover the cost.
