Aadhaar, KYC and many college and government forms accept photos up to 100KB. This guide shows the fastest way to resize any JPG or PNG to 100KB while keeping it sharp — free, no account, on any device.
How it works
No software, no account. Works for any target size — 100KB, 50KB, 20KB or any custom value.
Open Zappy Resize Image
Go to zappy.tools/resize-image/ — works on mobile and desktop. No signup needed.
Upload your image
Drag and drop or tap to browse a JPG, PNG or WebP (up to 25MB). The tool shows your current file size right away.
Switch to "By File Size" and set 100KB
Open the By File Size tab and choose your target so the image lands under 100KB. If the portal also wants exact pixels, set those on the By Pixels tab.
Download your resized image. Right-click → Properties (Windows) or Get Info (Mac) to confirm it's under 100KB before uploading.
Why it matters
100KB is the most common general photo limit across Indian forms — roomy enough for a clear, recognisable photo, small enough to upload fast. Aadhaar, bank KYC and most college admission portals sit at or near 100KB. A phone photo is several MB, so it has to be resized before it will go through.
No editor needed
You don't need an editor to hit a KB target. Here are the options — and why a dedicated tool is faster:
Photoshop / paid editors
Full control via Image Size and Export As, but paid, heavy to install and overkill for hitting a KB target.
MS Paint / Preview (free, fiddly)
Can change dimensions, but no "target KB" option — you resize, export, check, repeat until it fits.
Zappy — free, set the exact KB, any device
Go to Zappy Resize Image, open By File Size, set 100KB and download. No install, no account, no daily limit.
Common size targets
Different portals ask for different limits. Here are the most common ones — Zappy handles all of them with a single upload:
Need a smaller file? See resize image to 50KB or 20KB. Want to keep the exact dimensions? Use compress image to 100KB.
For India
Aadhaar enrolment and update forms, bank KYC and most college admission portals accept a photo around 100KB, often with a fixed pixel size too. Resize once and the same file works across all of them.
Upload to Zappy, switch to By File Size, set 100KB (and the required pixels on the By Pixels tab), download and upload directly to your portal.
Get the best result
100KB is comfortable for a clear photo — these basics keep it sharp:

Common questions
Open Zappy Resize Image in your phone browser, upload the photo, open the By File Size tab, set 100KB and download. Works on Android and iPhone — no app install needed.
Upload your photo to Zappy Resize Image, set 100KB on the By File Size tab and, if Aadhaar specifies pixels, set those on the By Pixels tab. Then download and upload to the UIDAI form.
Go to zappy.tools/resize-image/, upload your image, set the target to 100KB and download. No account needed at any step — completely free with no watermark.
Resize if the portal wants specific pixel dimensions. Compress if you must keep the current dimensions and only cut the file weight — see compress image to 100KB.
Crop tighter, lower the dimensions a little, or save as JPG instead of PNG. Running it through the By File Size tab once more also helps.
A clear, front-facing photo stays sharp at 100KB. Use JPG, crop to head and shoulders, and start from a good source for the best result.
