How to use Compress Image 20KB to 50KB
- Add your photo, or several. Phone photos, scans and screenshots all work; JPG, PNG, WebP, BMP and GIF are accepted.
- The window is already set: at most 50 KB, at least 20 KB. Change either number if your form asks for another range, and keep JPG unless it asks for WebP.
- Click "Compress to 20–50 KB". A big photo is brought down under 50 KB; a small one gets a higher quality, and more pixels only if it still needs them, until it reaches 20 KB.
- Check the size and pixels shown under each photo, then download it. Its name ends in "-20-50kb" so it is easy to find.
Why use Compress Image 20KB to 50KB
- Inside the window, both ends
- Files stay at or under 50,000 bytes and at or over 20,480, so they pass whether a form counts a kilobyte as 1,000 or 1,024 bytes.
- Small photos brought up honestly
- A photo under 20 KB is re-saved at a higher quality first; only if that is not enough are pixels added. Nothing is padded with filler bytes.
- Says when it cannot
- A tiny icon or a flat graphic may never reach 20 KB. The tool says so and shows the nearest size it could make instead of handing over a file that will be rejected.
- Batch friendly
- Compress a photo for each family member, or several attempts at the same photo, in one go, and download them together as a ZIP.
About this tool
Bank, exam and job portals in India and Pakistan often ask for a photograph between 20 and 50 KB. The State Bank of India's careers page, for example, asks for a photo of 200 × 230 pixels (preferred) between 20 KB and 50 KB, and a signature between 10 and 20 KB (checked 21 Oct 2026). A minimum keeps out pictures too small to show a face clearly: a 6 KB thumbnail would pass a maximum alone, but nobody could recognise the person in it.
That is why this page has two limits. A phone photo of several megabytes is reduced until it is under 50 KB, with quality lowered first and the size in pixels reduced only if it must be. A photo already under 20 KB, such as a small crop or a picture forwarded on WhatsApp, is saved again at a higher quality, and if that is still not enough its pixels are increased, up to twice its own width and height. If the form also sets exact pixels such as 200 × 230, resize the photo to them first with Resize Image; the note under each result shows the pixels it ended with.
Frequently asked questions
How do I reduce an image size to between 20KB and 50KB?
This 20kb to 50kb photo compressor works online, in your browser: add the photo on this page and click "Compress to 20–50 KB". The result is a JPG between 20 and 50 KB; its exact size and pixels are shown before you download it.
Why does my form reject a photo under 20 KB?
A very small file usually means a very small or blurry picture, and a minimum keeps those out. Forms that set one, such as the SBI recruitment pages, refuse any file below it, however clear it looks to you.
Will a small photo look better after it is made bigger?
No. Raising the quality and adding pixels makes the file reach 20 KB, but it cannot add detail the photo never had. If you have the original, larger photo, start from that one instead.
What if the tool cannot reach 20 KB?
Very small or plain pictures, like a logo on white, can stay under 20 KB even at the best quality and twice their size. The tool then says so and shows the nearest size; use a larger or more detailed picture.
What about the signature, which must be 10 to 20 KB?
Type 20 as the maximum and 10 as the minimum on the main Compress Image page, and the signature is made to fit that window the same way.
Does the photo leave my device?
No. The compression is done by your browser on your phone or computer, and the file is never sent anywhere.
