Image Compressor

Compress Photos to an Exact Size

Online forms, job portals and exam registrations often accept photos only below a limit such as 20 KB, 50 KB or 100 KB, while a phone photo is usually 2-5 MB. This tool shrinks images in your browser until they fit the size you set, or to the quality you choose. Your photos are never uploaded.

How to Use It

1. Drop one or more images on the box. JPG, PNG, WebP, HEIC, GIF and BMP all work.
2. Choose Target file size and enter the limit in KB (or tap 20, 50, 100, 200 or 500), or choose Quality and use the slider.
3. Pick JPG or WebP, and optionally a smaller Largest side.
4. Click Compress Images. One image downloads straight away; for several, download each one or all of them as a ZIP.

How the Target Size Works

The tool first lowers the JPG or WebP quality step by step to find the best quality that fits. If even low quality is too big, it reduces the pixel size a little at a time until the file fits. Each result shows the old and new size, the percentage saved and the final dimensions, so you can see exactly what changed.

Tips for Forms

• Check both limits in the form's instructions: many give a pixel size as well as a KB range. Set the size first with the Image Resizer, then compress.
• For passport photos and signatures, the Passport Size Photo Maker and Signature Resizer do the cropping and sizing in one go.
• Need a PDF under a limit instead? Use Compress PDF.

Limitations

Compression removes detail, so very small targets make photos look soft or blocky - zoom in before you upload. Transparent PNGs become JPGs with a white background; choose WebP to keep transparency. Animated GIFs keep only their first frame. Some portals also set a minimum size; if your file comes out too small, raise the target or the quality.
