Compress any photo to 5 KB
A lot of upload forms cap images at a fixed size, and 5 KB is one of the common limits — typically for tiny thumbnail avatars and the strictest upload fields. Instead of guessing quality settings, this page is preset to a 5 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 5 KB at noticeably better quality than an old-school JPEG.
How to reduce your image to 5 KB
- Add your image — drag & drop, paste, or choose a file.
- It targets 5 KB automatically. The tool is already in Target size mode set to 5 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 5 KB while staying sharp.
- Download the result — that's it.
Tip for very small targets
Hitting a tiny size like 5 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 5 KB becomes easy with quality to spare.

Frequently asked questions
How do I compress an image to 5 KB?
Open your photo in the tool above — it is already set to a 5 KB target, so it compresses to roughly 5 KB instantly. Switch the format to WebP for an even smaller file, then click Download.
Can I compress a JPG or PNG to 5 KB without losing much quality?
For most photos, yes. The tool lowers the quality just enough to reach about 5 KB. For a very small 5 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 5 KB — what should I do?
Very large or highly detailed photos can't always reach 5 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 5 KB.
Is compressing to 5 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.
