We tested it: three phone photos to 500 KB
We ran three real 12-megapixel phone photos through this page in Chrome on an ordinary laptop. Here's exactly what came out:
| Photo | Original | Result | Dimensions | Time |
|---|---|---|---|---|
| Pixel 2 photo | 4.16 MB | 498 KB | 1386×1848 | 1.2 s |
| iPhone 6 Plus photo | 3.51 MB | 497 KB | 1386×1848 | 1.5 s |
| Galaxy S7 Edge photo | 3.97 MB | 448 KB | 1848×1386 | 0.5 s |
500 KB keeps about 1390×1850 pixels, sharp on a full HD screen. 400 KB gave 1239×1652 and 800 KB gave 1753×2337.
The Galaxy photo, a night scene with lots of dark sky, came in well under the limit at the same dimensions. Simple scenes need fewer bytes.
How sharp is a 500KB photo?
At 500KB a full phone photo keeps about 1,390×1,850 pixels, sharp on a full HD screen and fine for a small print. Often the only change you'll notice is the file size.
Documents and scans
For a scanned certificate or ID, 500KB keeps small print and stamps readable. Crop away the background around the paper first so the space goes to the document itself.
Frequently asked questions
Will compressing to 500KB lower the quality?
Barely. At this size the tool can keep high JPG quality and most of the original resolution.
My photo is already under 500KB — what happens?
It's re-saved as a clean JPG at the best quality that stays under the limit.
Can I do many photos at once?
Yes — select them together and download all as a ZIP.
