How to use Compress image to 500 KB
- 01Add one or manyPhone photos, screenshots, HEIC, PNG or WebP.
- 02Leave the defaultsTarget is Under 500 KB; Largest side shrinks only if it must.
- 03Save the JPGsEach file is at most 500,000 bytes.

A loose limit, a light touch.
Half a megabyte is a generous budget for one picture. Smaller images are saved at our highest JPEG quality with every pixel kept; a big camera photo is trimmed only as much as the limit needs.
Compress image to 500KB for uploads that leave plenty of room but still turn away a straight-from-camera file. Profile photos on job sites, attachments on support forms, pictures in marketplace listings and photos of documents on government portals often sit around this size. At 500 KB the tool rarely has to give up much, so the main aim is simply to get under the line.
What happens to different pictures
- A passport-size crop or a small screenshot is far under 500 KB already. It is saved again at 92% JPEG quality at its full pixel size.
- A photo that was sent through a chat app has usually been shrunk once. It normally fits without any further loss you could see.
- A full-resolution photo from a modern phone camera is often several megabytes. The tool lowers quality first and, if that is not enough, reduces the pixel size a step at a time until it fits.
Choosing Largest side
With a 500 KB budget the default, Shrink only if needed, is the right choice for documents and for photos you might crop later, because it keeps the most pixels.
Max 2000 px is useful for photos that will only be looked at on a screen, such as a listing or a profile. A 2000-pixel picture fills a laptop display, and with fewer pixels to store the JPEG quality stays high, which avoids blotchy skies and skin.
Photos of documents at 500 KB
This size suits a phone photo of a full page: a certificate, a utility bill, a lease page. Small print, stamps and signatures usually stay readable. Crop away the table and fingers around the page first so the pixels go to the paper.
If the form wants several pages in one file, an image is the wrong format. Put the pages into a PDF with Image to PDF and bring it under the limit with Compress PDF to 500 KB.
500 KB or a smaller target?
Use the number the form gives. Going lower than you need only throws detail away. If the box says 200 KB or 100 KB, switch Target size to that value; the Compress image to 200 KB and 100 KB pages explain those trade-offs.
If you are sending pictures by email with no stated limit, 500 KB per photo keeps a message with several attachments to a modest size while each picture stays sharp.
What the result does not keep
- Transparency. PNGs with a see-through background are given a white background, because the output is always JPG.
- Camera details and location. The new JPG is drawn from the pixels only.

Questions
Do my photos go to a server?
No. Each picture is processed by your browser and stays on your device.
Will people notice the photo was compressed?
Rarely. At 500 KB most photos look the same as the original at normal viewing size.
Is 500 KB the same as 0.5 MB?
Yes, when a megabyte is counted as 1,000 KB. Our file is at most 500,000 bytes, so it passes a 0.5 MB limit either way.
How do I compress a photo to 500 KB without losing quality?
Keep Largest side on the default and start from the camera original. Most photos then lose so little at 500 KB that the difference is hard to find.
Can I compress an image to 500 KB on an iPhone?
Yes. Open the page in Safari, pick the photo (HEIC is fine) and save the JPG to Files.
Why is the result smaller than 500 KB?
When the picture already fits at the tool’s top quality, there is nothing to gain by making the file bigger, so it stops there.
Can I get a PNG under 500 KB instead?
This page always saves JPG. To change format without a size target, use the PNG converters.
