Use it safely
When should you choose 100KB?
| Situation | Best action |
|---|---|
| Form says “100KB or less” | Use the 100KB preset and download the JPG output. |
| Profile or application photo | Crop extra background first, then compress to keep face detail clearer. |
| Form shows exact pixels | Resize or crop first, then compress the resized image to 100KB. |
| Need better quality than 50KB | Use 100KB when the portal allows it, because it preserves more detail. |
There is no universal official 100KB rule for every website. Always follow the exact file size, format, and pixel instructions shown on your current form.

FAQ
Common questions
How do I compress an image to 100KB JPG?
Upload your image, keep the 100KB preset selected, click Compress, then download the JPG. If your form also gives exact dimensions, resize or crop first and then compress.
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.
Should the 100KB output be JPG or PNG?
JPG/JPEG is usually the safer choice for 100KB photo uploads because it compresses images well. If your form asks for PNG or another format, follow that form.
Should I resize before compressing to 100KB?
Yes, if your original photo is large or the form gives exact width and height. Resizing first usually gives a cleaner 100KB result than heavy compression alone.
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 100KB?
Some images have too much detail or are already compressed. Crop extra background, resize smaller, then run the 100KB preset again.
Can I use this for passport, admission, or job form photos?
Yes, if the form allows a 100KB image and does not require a different exact size. Always check the form’s own KB, format, and dimension rules before uploading.
Is this tool really free?
Completely. No account, no watermarks, no usage caps. Files stay on your device.
