What this page is for
When a site or form caps uploads at 500KB, this page aims for that limit while keeping quality as high as possible. Add multiple images and process them with the same 500KB setting.
Common uses include ID photos for applications, document portals, and internal tools that reject anything over 500KB.
How to get under 500KB
Add your images—the target is already set to 500KB. Press “Compress all (under 500KB)” and the tool adjusts quality automatically.
If a file still won’t fit, combine long-edge resize (for example 1920px or 1600px). For stubborn PNGs, try WebP as the output format.
Images that are already 500KB or smaller are left unchanged, so you don’t degrade files that already meet the limit.
How does 500KB affect quality?
500KB is a common upload cap. A single phone ID photo often fits with little visible loss.
Large landscape shots or text-heavy PNG screenshots may need lower resolution or quality. If text looks soft, try a long edge around 1600px before compressing.
JPEG suits photos, PNG suits graphics or transparency, and WebP often wins on size at similar quality. At a hard 500KB cap, format choice matters.
If you still can’t get under 500KB
Very large originals or detailed transparent PNGs may miss 500KB even at low quality. Lower the long-edge limit or convert to WebP/JPEG.
If it still fails, the source resolution may be too high—capture a smaller photo, or crop screenshots to the area you need.

Frequently asked questions
How do I compress to under 500KB?
This page already sets the target to 500KB. Add images and press “Compress all (under 500KB)”—quality is adjusted automatically to aim for that limit.
Can I hit exactly 500KB?
No. The tool targets 500KB or less and prefers the highest quality that still stays under the cap—not an exact byte match.
How much will quality change at 500KB?
It depends on resolution and content. A single ID-style photo often looks fine. Text-heavy PNGs or large prints show more change when resolution is reduced.
What if a PNG won’t go under 500KB?
PNGs are often larger than photos. Switch output to WebP or JPEG, and/or enable long-edge resize. If it still fails, the source may simply be too large.
Where are the compressed files stored?
