How to compress an image
- Choose or drop your images (JPG, PNG, WebP).
- The target is already set to 100 KB; change it if you need another size.
- Tap Compress.
- Download each image or all of them in a ZIP.
What is this tool for?
A limit of 100 KB is common in online forms, ID and passport photos, exam registrations and government portals. This tool finds the best quality that fits under 100 KB and, if the photo is still too heavy, lowers its dimensions a little until it fits.
Everything runs on your device, so personal photos and document scans are never uploaded. The result also has no metadata, such as camera model or GPS location.
Limits to keep in mind
- Compressing to a very small size lowers the quality and, when needed, the dimensions of the image.
- Transparent PNG images become JPG with a white background unless you choose PNG or WebP as the output format.
- HEIC photos from iPhone and some other formats can't be read; convert them to JPG first. Very large photos, over 16 megapixels, are reduced automatically.
Frequently asked questions
How do I reduce an image to 100 KB?
Drop the image and tap Compress. The target is already 100 KB. The tool looks for the highest quality that stays under that size.
Will my image lose quality?
A little, since a smaller file needs more compression. The tool keeps the best quality that still fits in 100 KB and only reduces dimensions when needed.
Are my images uploaded to a server?
No. Compression runs in your browser, on your device. Your images are not sent anywhere.
What if it cannot reach 100 KB?
Very large or very detailed images may need smaller dimensions. Pick a smaller maximum width or height in the options and compress again.
