Compress any photo to 10 KB
A lot of upload forms cap images at a fixed size, and 10 KB is one of the common limits — typically for very strict upload fields and small ID thumbnails. Instead of guessing quality settings, this page is preset to a 10 KB target: drop your photo in and the compressor shrinks it to roughly that size on your device, then shows you the exact before → after result.
It works on JPG, PNG, and WebP. If you only need the file to be small (not a specific format), leave the format on Auto or pick WebP — WebP reaches 10 KB at noticeably better quality than an old-school JPEG.
How to reduce your image to 10 KB
- Add your image — drag & drop, paste, or choose a file.
- It targets 10 KB automatically. The tool is already in Target size mode set to 10 KB, so it compresses straight to it. Change the number any time.
- Still too big? Turn on Resize and lower the longest edge — the single biggest lever for getting a large photo under 10 KB while staying sharp.
- Download the result — that's it.
Tip for very small targets
Hitting a tiny size like 10 KB on a 12‑megapixel phone photo by quality alone can blur it. The fix is to resize first: a photo doesn't need to be 4000px wide for a form. Cap the longest edge to ~800–1200px, and 10 KB becomes easy with quality to spare.
What fits in 10 KB?
10 KB is a very tight budget — enough for a small thumbnail or a simple graphic, not a full-detail photo. As a rough guide a photo keeps usable quality only at about ~160–220 px square (0.02–0.05 MP); push the dimensions higher and it gets visibly soft. The exact result depends heavily on how detailed the picture is.
- Photo (roughly)
- ~180–250 px on the long side — about 0.02–0.05 MP
- Simple graphic (roughly)
- ~320–580 px square
- A flat logo, signature, or simple icon survives much larger at this size — roughly ~320–580 px square — because solid colours compress far harder than a photo.
- Real-world caps this tight are usually signature fields and a few strict government-exam photo uploads; resizing the longest edge down first is the only reliable way to hit it cleanly.
These are rough estimates from a typical compression rate, shown as ranges — your real result depends on the image and the format you choose.

Frequently asked questions
How do I compress an image to 10 KB?
Open your photo in the tool above — it is already set to a 10 KB target, so it compresses to roughly 10 KB instantly. Switch the format to WebP for an even smaller file, then click Download.
Can I compress a JPG or PNG to 10 KB without losing much quality?
For most photos, yes. The tool lowers the quality just enough to reach about 10 KB. For a very small 10 KB target on a large image, also turn on Resize to cap the longest edge — that is the biggest single lever and keeps the result sharp.
My image is still larger than 10 KB — what should I do?
Very large or highly detailed photos can't always reach 10 KB on quality alone. Enable Resize and lower the longest edge (e.g. to 800–1200px), and prefer WebP — together they bring almost any image down to 10 KB.
Is compressing to 10 KB done online or on my device?
The compression runs in your browser, so it is fast and works the same on phones and laptops. See our privacy policy for how data is handled.
