How to use Compress Image to 100KB
The target is set to 100 KB. Change it if the portal states a different maximum.
Click "Choose images" and pick your photo or document image.
Click "Compress", check the green "Under 100 KB" tick and the pixel size, then download.
When to use Compress Image to 100KB
- Passport Seva photo uploads. Online passport and visa forms have commonly allowed photos up to about 100KB. Check the current limit on the official site.
- Visa applications. Many visa portals ask for a photo under 100KB or 240KB with set pixel dimensions.
- University applications. Indian and overseas universities often cap the photo at 100KB.
- Document photos. An Aadhaar or PAN card photo taken on a phone can be brought under 100KB and still be readable.
Pixel sizes that work at 100KB
At 100KB there is room for a detailed photo. Visa portals often want a square or 35 x 45 mm shape, so crop to the right shape first and then compress.
| Requirement | Typical pixels | Notes |
|---|---|---|
| US visa style photo | 600 x 600 px | Square, plain white background |
| India passport style photo | 35 x 45 mm (413 x 531 px at 300 DPI) | Face should fill most of the height |
| Document scan | About 1200 to 1600 px wide | Text stays readable |
Use the Passport Photo Maker if you also need the exact shape and a white background.
Tips for official photos
- Do not use filters or beauty modes; portals may reject edited photos.
- Keep the background plain and evenly lit. Shadows behind your head add file size and can cause rejection.
- If the portal wants an exact pixel size, resize first with Image Resizer, then compress here.
Limits and privacy
- Up to 50 images at once, 25MB each. JPG, PNG, WebP, AVIF.
- Output is JPG by default, which every passport and visa portal accepts.
- Results are marked green when under the target and red if the photo needs smaller dimensions.
- Images are decoded and re-encoded by your browser using the canvas API. Nothing is sent to a server, and closing the tab clears everything.
Frequently asked questions
How do I reduce a photo to 100KB?
Keep the target at 100 KB, choose the photo, and click Compress. Most phone photos only need lower JPG quality plus a moderate resize to fit. The page shows the new size and pixel dimensions of each file, and a green tick once it is under 100KB.
How do I compress a photo to 100KB on mobile?
Open the page in Chrome or Safari, tap "Choose images", select the photo from your gallery, tap Compress and then Download. The tool runs inside the browser, so there is nothing to install and the photo is not sent anywhere.
Will a 100KB photo be blurry?
No, 100KB is enough for a clear photo at passport and visa sizes and for most document photos. You will only notice softness if a very large, detailed image is kept at full size, which is why the tool reduces dimensions when needed.
Which forms ask for this size?
Passport and visa applications, university admissions and many overseas job portals commonly ask for photos under 100KB. The exact limit and the required dimensions vary, so check the official instructions for your application before uploading.
Are my photos sent to a server?
No. Your photo is processed by your own browser and is never sent to a server. This is important for passport and identity photos, which should only go to the official portal.
