How to use

Add your photo: tap "choose files", drag it onto the box, or paste it.
Keep the 50 KB target, or tap "20–50 KB" if your form also has a minimum size.
Check the new size shown under the photo, then download it.

The same photo before compression, 1.1 MB — The same iPhone photo before and after compressing it to 50 KB with this tool's settings. The compressed file is 387 × 516 px; it is never shown larger than that.

The same photo after compression to 50 KB, 42.5 KB, shown at its real size of 387 × 516 px — The same iPhone photo before and after compressing it to 50 KB with this tool's settings. The compressed file is 387 × 516 px; it is never shown larger than that.

Which pixel sizes fit in 50 KB

A typical phone photo is 2 to 5 MB, so it has to become 40 to 100 times smaller to fit in 50 KB. The tool keeps the quality clean and makes the picture smaller instead. This is what our sample photos became at 50 KB:

Photo	Result at 50 KB
iPhone, landscape	655×491 px, 43.5 KB
iPhone, portrait, detailed	387×516 px, 48.8 KB
1920×1440 photo	516×387 px, 43.6 KB

That is plenty for an application photo or an upload preview. If your form asks for exact pixel dimensions, open Advanced options and tick “Keep the original width and height”; the tool then lowers the quality instead. Cropping the photo first (for example to your head and shoulders) leaves more of the 50 KB for the part that matters.

The 20–50 KB range

Many application forms want a photo between 20 KB and 50 KB, and some reject files that are too small. The 20–50 KB button sets both limits at once:

A large photo is compressed until it is under 50 KB.
A photo that is already small is made a little larger, first by raising the quality and then, if needed, the pixel size, until it reaches 20 KB.
A photo already inside the range is returned as it is, with hidden details such as location removed.

Why the result is just under 50 KB

Sizes are counted two ways: some systems count 1 KB as 1,000 bytes, others as 1,024. To pass both, a 50 KB result is never more than 50,000 bytes, and the tool picks the best-looking version below that line. Windows shows such a file as 49 KB or less, which is under any 50 KB limit.

Frequently asked questions

How do I compress a photo to 50 KB on my phone?

Open this page in your phone's browser, tap "choose files" and pick the photo from your gallery. It is compressed to 50 KB or less right away, and the Download button saves it to your Downloads or Files app. Nothing needs to be installed.

Can I get a file of exactly 50 KB?

Not to the exact byte, and you do not need to. Forms check that a file is not more than the limit, so the tool aims for the best-looking version that still fits, which is usually a little under 50 KB.

How do I make an image between 20 KB and 50 KB?

Tap the "20–50 KB" button under the target sizes. The tool then keeps the file under 50 KB and, if your photo is very small, makes it bigger until it is at least 20 KB.

Will the form accept my 50 KB photo?

The size will pass, because the result is never more than 50,000 bytes. Forms often have other rules too, such as JPG format, a pixel size or a plain background, so read the instructions on the form as well.
