Resize image to 20KB–50KB

Many exam and job portals accept a photo only if it is between 20 KB and 50 KB. Drop your photo here: Arche saves a JPG inside that range at the highest quality that fits, and pads a file that comes out too small. Your files never leave your device.

Form preset

Maximum size (KB)

Each file comes out between 20 KB and 50 KB. Files that would be smaller are padded up; the picture stays the same.

Form requirements: minimum, pixels, DPI

Minimum size (KB, optional)

Width (px)

Height (px)

Fill in both for an exact pixel size, as many exam and ID forms ask.

DPI (optional)

Black and white

For forms that ask for a black-and-white signature.

Allow smaller dimensions

When the quality would have to drop below 60, scale the image down instead until it fits.

Output format

Your browser decodes and re-saves each image. Nothing is sent to Arche's servers, and re-saving drops EXIF metadata such as GPS location.

Guide

Good to know

How Arche lands between 20 and 50 KB

Arche saves the photo as JPG at the highest quality that stays under 50 KB, counting 1 KB as 1,000 bytes. If the result is under 20 KB, as small scans often are, it tries full quality and then adds a padding block inside the file, this time counting 1 KB as 1,024 bytes, so the file passes portals that count either way. The padding does not change the picture.

Exact pixels as well as KB

IBPS and SBI forms also ask for a 200 × 230 pixel photo. Pick the form under Form preset, or enter the width and height under Form requirements: Arche crops the middle of your photo to that shape, or fits the whole photo with a white border, and then brings it into the range.

Photo and signature sizes for common forms

Pick one of these under Form preset and Arche sets the size range, pixels and DPI for you. The figures come from each body's published upload instructions, checked in November 2026. They can change between notifications, so check yours before you upload.

FAQ

How do I make a photo between 20 KB and 50 KB?

Drop it on this page: the range is already set, and you get a JPG between 20 and 50 KB at the best quality that fits. If the form also lists pixel dimensions, enter them under Form requirements first.

Why was my small file made bigger?

A form that asks for 20 to 50 KB rejects a 12 KB file just as it rejects a 60 KB one. Arche first saves it again at full quality; if it is still under 20 KB, it adds a padding block that image viewers and portals skip, so the picture looks exactly the same.

Are my images uploaded?

No. The conversion runs inside your browser, so your images stay on your device. Files are only uploaded if you choose to optimize them with Arche, and those are deleted within 48 hours.

What is Arche?

Arche makes JPEG, PNG and WebP images smaller without changing their format or pixel size, and strips metadata such as EXIF location. It is free without an account; Pro raises the batch limits.
