Resize an image to 500 KB
At five hundred kilobytes quality has stopped being the question. A photograph at this size looks the same as the original to anyone viewing it on a screen. A 500 KB cap is nearly always about an upload or attachment limit rather than about how the picture looks, which changes what you should adjust to meet it.
No images yet. Add a photo and set the size you need.
Dimensions are the lever, not quality
When the target is small, lowering quality is the only way to get there. At 500 KB you have the opposite situation: the file is probably too large because it is enormous in pixels, not because it is saved at high quality. A recent phone photo can be twelve megapixels and several megabytes. Reduce it to around two thousand pixels on the longest side and you will often be under 500 KB with the quality left near maximum and nothing visibly lost.
Where this limit shows up
- A photograph attached to a CV, where it should still look professional.
- Profile pictures on sites that cap the upload rather than the appearance.
- Email, where a few photos at 500 KB stay well within any attachment limit.
- Portals that accept a generous size but reject anything above a round number.
When not to resize at all
If the picture is going to be printed, or edited later, or is the only copy of something you cannot photograph again, keep the original and resize a duplicate. Compression is not reversible: the detail removed to reach 500 KB cannot be recovered from the smaller file, however large you make it again afterwards.
Steps
- Choose your photo.
- The limit on this page is already 500 KB.
- Check the new size. The picture should look unchanged.
- Press Download, and keep your original file.
Questions
Will the photo look worse at 500 KB?
Not noticeably on a screen. At this size the compression is light enough that the result looks like the original.
Can I get the original quality back later?
No. Compression removes detail permanently. Always keep the original file and resize a copy.
Why is my phone photo several megabytes?
Phone cameras capture far more pixels than any screen displays. Reducing the dimensions to what will actually be shown is usually enough to reach 500 KB on its own.
