Resize Image to 100KB

Upload your image, keep the target on 100KB, and the tool finds the highest JPG quality that stays under 100KB, reducing dimensions only if needed. Then download it.

Yes. With twice the byte budget, the compressor keeps more detail, so a 100KB image looks noticeably sharper than the same photo at 50KB. Choose 100KB whenever your form allows it.

Definitely. 100KB is a good balance of quality and load speed for web photos. Resize to your display width first for the crispest result.

No. Every step — resizing, cropping and compression — happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device, and nothing is stored or transmitted.

Open the "Need exact width, height or quality?" section and reduce the width and height — a smaller image reaches a tiny KB target far more easily. Make sure the output format is JPG, and start from the original photo rather than a screenshot. If a target is physically impossible, the tool shows the smallest clear result it can make instead of a broken file.

Choose JPG for photographs and most form uploads because it gives the smallest file size. Use PNG only when you need a transparent background or razor-sharp line art. WebP gives excellent compression but some older government portals do not accept it — check the form requirements first.
