Compress images to under 50 KB for application forms
Shrink candidate photographs and certificates to under 50 KB. Meet strict upload requirements for admission forms, recruitments, and government websites.
How it works
Upload your photo or document
Your image is read locally in the browser.
Target ceiling set to 50 KB
The tool automatically finds the highest possible visual clarity that fits under 50 KB.
Compress
Fast client-side encoding reduces byte size without sending data anywhere.
The picture never leaves your device
Compressing or converting a photo usually means sending it to somebody else's computer and getting a new one back. Here the work happens in the page you are already looking at: your browser opens the file, the tool rewrites it, and the browser hands you the result.
- Opened from your disk by your browser — not sent anywhere first.
- Held in the tab while the tool works, then dropped.
- Saved to your device by your browser, not by a link to a server.
- Closing the tab clears the working copy completely.
- No account, so nothing is ever attached to an identity.
- No tracking of what you worked on or what was inside the file.
There is no queue and no waiting room. The picture is worked on in front of you and released the moment the tab closes. You can read more about how the conversion runs on your own device, or check our guide to verifying it in DevTools.
What people use it for
Shipping a lighter page
Hero images are usually the heaviest thing on a site. Getting them smaller before they reach your CMS is the fastest performance win available.
Sending photos on a weak signal
On hotel Wi-Fi or a poor mobile connection a full-resolution photo can sit at sending for minutes. A smaller copy goes through in seconds.
Preparing marketplace listings
Selling platforms set their own caps on size and dimensions. Get inside them before you start filling in the form.

When something goes wrong
Damaged files, and formats outside the list above, stop with a plain message rather than a spinner that never finishes. If a picture opens in your gallery it will normally open here.
The format is not supported. Convert it to PNG or JPG first, or try one of the other image tools.
Why not an upload site
An upload-based tool is a form that posts your picture to someone else's machine. Take that step out and a lot of small annoyances disappear with it.

Questions
Will text on documents stay readable?
Yes. The algorithm preserves edge contrast and sharpness so text, numbers, and facial features remain legible.
Can I convert PNG to JPG while compressing to 50 KB?
Yes. JPG is selected by default, which is the most widely supported format across all recruitment portals.
Are my documents secure?
Completely secure. No files are uploaded to any server or cloud service. It works completely offline once loaded.
Is there a file size limit?
No fixed limit is imposed by the tool. The practical ceiling is how much memory your device has free, because the whole job runs inside this browser tab.
Does it work without an internet connection?
Yes, once the page has loaded. Nothing is fetched while you work, so a dropped connection does not interrupt a run.
Do I need an account or an email address?
No. There is nothing to sign up for, and nothing is ever attached to an identity because no file leaves your device.
