When a form caps the photo at 20KB, this tool walks your image down to that limit, trimming the file until it slips under 20 kilobytes while keeping as much clarity as the budget allows.
Original
≤ 20 KBThe whole process runs locally in your browser, so your photo is never uploaded during the resize.
How to use Resize Image to 20KB
Using Resize Image to 20KB takes only a few seconds and just four simple steps — no sign-up, no software, and nothing to learn:
- Add your image: Pick a JPG, PNG, or WebP file.
- Target 20KB: The size is preset to 20KB; adjust if your form differs.
- Compress: The tool searches for the best quality that fits under 20KB.
- Download: Check the new size, then save.
What you can do with Resize Image to 20KB
Resize Image to 20KB is built to do one job well, and gives you everything you need to get it exactly right:
Exact 20KB target. Lands as close to 20KB as the image allows.
Nothing leaves your device. Resizing happens in the browser, so ID photos stay private.
Mixed formats. Feed it JPG, PNG, or WebP — output is a compact JPEG.
Free. No account, no watermark, unlimited use.
For strict 20KB upload limits
Exam and job portals often cap photos at 20KB. Instead of guessing quality settings, let the tool find the level that passes the size check the first time.
Whether you need it once or every day, Resize Image to 20KB keeps the process quick and predictable. Because it focuses on a single task, there are no crowded menus to wade through — you open the page, set what you need, and get your result. That simplicity is exactly why a dedicated image tool beats a heavyweight editor for a job like this.
Everything runs in your browser
Unlike most online tools, Resize Image to 20KB never uploads your image to a server. The moment you choose a file, it is processed right here in your web browser using your own device's power. Nothing is sent over the internet, nothing is stored, and nothing is shared with anyone.
That gives you two real advantages. First, it is private: sensitive documents, ID photos and personal files never leave your computer or phone. Second, it is fast — there is no slow upload or download round-trip, so even large files are handled almost instantly. And it is completely free, with no watermark added to your result and no account required.
