Online image compressor —
compress to exact KB
Set 100KB, 50KB, or any custom limit — not a vague “smaller file.” Drop one or many; done in seconds in your browser.
Need a preset for a strict portal? Use compress image for NADRA under 100KB, compress visa photo to 350KB, or compress image for FBISE under 50KB. Need iPhone HEIC photos as JPG first? Use the HEIC to JPG converter or the full image converter.

Why compress to exact KB?
Government and job portals reject uploads when the file is even slightly over the limit. Exact-KB compression beats generic “reduce size” tools when you need a specific ceiling.
- NADRA / CNIC: under 100KB for id.nadra.gov.pk
- PPSC: 25KB photo plus 3.5 × 4.5 cm resize
- FBISE: 50KB exam uploads
- Visa / passport: visa photo limits

FAQ
Common questions
How to make photo size less than 100KB?
Upload your photo, tap the 100 KB preset (or type a lower number), then Compress. For NADRA-style uploads see compress image for NADRA.
How to reduce picture size to 100KB?
Same workflow: drop the image, set target to 100 KB, compress, download JPG. The tool adjusts quality automatically until it hits your KB target (within about ±2%).
How do I compress an image to 50KB?
Drop your image, click the "50 KB" button, then hit Compress. The tool automatically adjusts quality to bring your image as close to 50KB as possible.
Is my image uploaded to a server?
No. All compression happens in your browser using JavaScript. Your image never leaves your device — not even for a millisecond.
What image formats are supported?
JPG, PNG, WebP, and HEIC (iPhone format). All output is saved as JPG for best compression.
Can I compress multiple images at once?
Yes. Drop or select multiple images at once and hit "Compress all". Download one image individually or use "Download all (ZIP)" to save the batch as a ZIP.
Does it work with iPhone HEIC photos?
Absolutely. HEIC files are auto-converted to JPEG before compression — no extra steps needed.
Why is my compressed image still larger than the target?
Some images — especially small or already-compressed ones — can't shrink further without becoming unusable. The tool warns you when this happens.
Is there a file size limit?
No server limit. Very large files (50MB+) may be slower depending on your device since everything runs locally.
Can I use this for passport or visa photos?
Yes. Enter the KB limit from your application form, compress, and download. Works great for visa, passport, and government portal uploads.
Does it work on mobile?
Fully. Works on Android and iOS browsers. Compress photos directly from your phone camera.
Is this tool really free?
Completely. No account, no watermarks, no usage caps. We make money from non-intrusive ads.
