Compress photo to 500 KB

To compress a photo to 500 KB: upload your image and set 500 KB in the “To size” mode. 500 KB is a comfortable size for website images — pages load fast while quality stays high, usually with no visible artifacts. No sign-up, batch supported.

Upload up to 20 images at once with a total size of up to 30 MB — completely free, no sign-up required. Create an account or to compress up to 30 images with a total size of up to 50 MB.

When exactly 500 KB is required

500 KB is no longer about squeezing under a cap — it is optimisation without compromise. The threshold suits hero images and full-width banners, portfolios for photographers and designers, photos destined for 10×15 cm prints, panoramas and shots dense with fine detail.

At this weight compression stops being visible even under close inspection: 500 KB is enough to preserve fabric texture, foliage and smooth gradients in a sky — the very things that fall apart first at smaller limits.

The only weight that holds up in print

Of all the thresholds on this site, 500 KB is the first one fit for paper. A 10×15 cm print at the standard 300 dots per inch needs roughly 1200×1800 pixels at high quality — which is precisely 500–800 KB. At 100 KB the same print picks up softness and banding across gradients; at 500 KB it does not.

Larger formats need more headroom still: a shot destined for A4 is better left uncompressed, using lossless mode instead — it strips surplus metadata and repacks the file without touching a single pixel.

Convenient for batch processing

Unlike strict caps, 500 KB can be applied to a whole folder at once without sorting through what is in each frame. A portrait fits with room to spare, a detailed landscape lands right on the edge, and both come out visually clean. Upload a batch of files or a ZIP archive, set 500 KB, and each shot is fitted individually; the result downloads as a single archive.

What compressing to 500 KB actually produces

Source image	Original size	Result	What you notice
Hero banner, 2560×1440	3 MB	500 KB	No difference even on a 4K monitor
Photo for 10×15 print, 1200×1800	2 MB	500 KB	Suitable for photo paper
Phone landscape, 4032×3024	5 MB	500 KB (−90%)	Foliage and sky clean, no artifacts
Folder of 20 shots	80 MB	10 MB total	Each file fitted individually

This is the upper bound of meaningful target-size compression. If you need maximum quality, pick lossless mode instead: it cuts 20–40% of the weight through metadata and repacking, without touching the pixels themselves.

Frequently asked questions

Yes — upload a batch of files or a ZIP archive and every file is fitted to 500 KB. The result can be downloaded as a single ZIP.

For 10×15 cm, yes — provided the resolution is around 1200×1800 pixels. For A4 and larger the headroom runs out: there it is better not to set a target weight at all and use lossless compression instead.

For a website, usually yes: most content images live happily at 200 KB, and less again in WebP. Keep 500 KB for hero images, portfolios and anything that will be inspected closely or printed.

A 500 KB target is reached by lowering quality — imperceptibly, but the pixels do change. Lossless mode leaves pixels entirely alone: it strips metadata and repacks the file, typically winning 20–40% of the weight rather than 90%.

It is left untouched. That is particularly handy for batch runs: in a folder of mixed files only the heavy shots get processed, while the already-light ones keep their original quality.
