Resize an image to an exact size in KB
Many online forms only accept photos under a size limit: 20 KB, 50 KB, 100 KB or 200 KB for a signature or photo on an application form, 1 MB or 2 MB on job portals. Type the limit in KB and the resizer finds the best quality that fits: it lowers the JPG quality step by step and, only if that is not enough, makes the picture smaller. Photos usually stay sharp down to about 50 KB.

JPG, PNG or WEBP?
JPG gives the smallest files for photos and is accepted everywhere. PNG keeps transparency and sharp edges in screenshots and logos but makes bigger files, so for a size in KB choose JPG. WEBP is smaller than JPG at the same quality and works on websites and in modern apps. To shrink many photos at once without changing their size in pixels, use Compress JPG.
Frequently asked questions
How do I resize an image to 50 KB?
Select the image, choose File size (KB), type 50 and click Resize image. The result is the best-quality JPG under 50 KB; download it and upload it to your form.
Will resizing reduce the quality?
Making a picture smaller in pixels or in KB always removes some detail, but the resizer keeps as much quality as the target allows. Photos usually look the same down to about 100 KB.
Can I make an image bigger?
Yes, type a larger width and height. The picture gets more pixels but no new detail, so a big enlargement can look soft.
Does it work on iPhone and Android?
Yes. Open this page in Safari or Chrome on your phone and select a photo from your gallery. iPhone HEIC photos open in Safari; in other browsers convert them first with HEIC to JPG.
Is my photo uploaded?
No. The image is resized in your browser and never sent to our server.
Is there a watermark or a limit?
No watermark, no sign-up and no limit on how many images you resize.
