Compress image to 200KB

Get a photo, scan or signature under 200KB for an upload form, an email or a website. Arche lowers the quality first and scales the image down only when the picture would turn blocky. Your files never leave your device.

Target size (KB)

Each file comes out at or just under this size. 1 KB = 1,000 bytes.

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 it gets under 200KB

Each image is saved as JPG or WebP at the highest quality that fits under 200KB. When that would mean a blocky picture, Arche scales the image down instead, a step at a time, and keeps the quality at 60 or above: a slightly smaller image is far easier to read than a blurry one. Every result shows its file size, quality and pixel size.

Where 200KB limits come up

Job portals, college applications, marketplaces and website forms commonly allow up to 200 KB per image. That is enough for a sharp photo 1,200 to 1,600 pixels wide, so Arche rarely needs to reduce the pixel size at all.

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

Frequently asked questions

Will the file be exactly 200KB?

It will be just under 200KB, usually within a few percent. Upload forms check that a file is not larger than the limit, so slightly under is what you want. Arche counts 1 KB as 1,000 bytes, so the file also passes forms that count 1 KB as 1,024 bytes.

Can I keep the same width and height?

Yes: turn off Allow smaller dimensions. Arche then only lowers the quality, and tells you if an image can't get under 200KB at its current size. If a form also asks for exact pixel dimensions, enter them under Form requirements.

What if the form also has a minimum size?

Open Form requirements and fill in the minimum, or pick your form under Form preset. Arche keeps each file between the two sizes and, if a file would come out too small, pads it up without changing the picture.

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.
