How do I get an iPhone photo under 100 KB?

Drop it here and the tool does it for you. A 12 MP photo can't fit in 100 KB at full resolution, so we reduce the quality to a sensible floor and then shrink the dimensions until it fits.

Will my photo get smaller in pixels?

Almost certainly. How much depends on the photo: plain backgrounds keep more pixels than busy scenes, and the result shows the final dimensions before you download.

The portal says max 100 KB. Will this pass?

Yes. We count 100 KB as 100,000 bytes, which is a little under the 102,400 bytes some forms use, so the file passes either way.

The form also needs exact pixel dimensions. What should I do?

Crop or resize to the required dimensions first, then compress. A small, correctly sized photo usually fits in 100 KB with high quality to spare.

Should I choose JPG or WebP?

Use JPG for government, visa and exam portals. WebP is often a little smaller at the same quality, but many official forms only accept JPG or JPEG.

Is it safe to process an ID photo here?

Your photo is never uploaded. It's processed by your own browser, and GPS location is removed by default, which is exactly what you want for an identity document.

Compress HEIC to 100KB: ID, Visa and Exam Photos

Who needs a 100 KB photo?

More people than you’d think. The 100 KB limit is a classic on systems built years ago that never expected 12 MP phone cameras:

Passport and visa applications that ask for a digital photo upload
Exam and admission forms for entrance tests, scholarships and certifications
ID cards and staff badges on HR or university portals
Avatars and profile pictures on older forums and intranets

They all share the same problem. Your iPhone hands you a HEIC of 2 to 4 MB, and the form wants a JPG 30 times smaller.

What happens to your photo

Getting from megabytes to 100 KB takes two steps, and we try the gentle one first.

Lower the quality. We search for the highest JPG quality that fits, but never go below about 55. Below that, faces get blotchy.
Shrink the dimensions. If quality alone can’t reach 100 KB, which is normal for full-size photos, we scale the photo down just enough.

So expect your output to be noticeably smaller in pixels. That’s fine. Portals display ID photos at passport-photo size, not on a 4K monitor.

Tips for passing a strict portal

Crop before you compress

Most ID photo rules care about framing: head and shoulders, centred, a set aspect ratio. Use Crop HEIC with a preset like 4:5 or 1:1 first. Cropping throws away background pixels, which leaves more of the 100 KB budget for your face.

Match the required pixel size

If the form says something like “600 × 600 pixels”, resize to that exact size before compressing. A 600 px square fits comfortably under 100 KB at high quality.

Plain backgrounds help

A white or light grey wall compresses far better than a bookshelf. If you’re taking the photo yourself, it’s a free quality boost.

Check the format

Stick with JPG unless the form explicitly allows WebP. Some portals reject anything not ending in .jpg or .jpeg.

The units trap

Forms are inconsistent about what “100 KB” means: 100,000 bytes or 102,400. We aim under 100,000, so you never get the “file too large” error by a few hundred bytes.

Private by default

Identity photos are exactly the kind of file you shouldn’t send to a random converter’s server. This one never leaves your browser, and its location data is removed before you download.
