500 KB is a common email attachment and web-upload limit — big enough to keep a photo looking sharp, small enough to avoid "attachment too large" errors or slow page loads. This tool finds the right quality automatically.

Drag & drop files here, or
Up to 100 images, 25 MB each
Any JPG, PNG or WebP file — high-resolution camera photos included.
The target chip starts at 500 KB; adjust it if a different limit applies.
A clearly sharp, web-ready file at (or just under) 500 KB, ready to attach or upload.
At 500 KB, high-resolution photos usually retain their full pixel dimensions and only need a moderate quality reduction, so visible quality loss is minimal even on close inspection. This makes it a sensible default for portfolio images, email attachments, and web pages where load speed matters but so does visual quality.
Many email providers reject or silently compress attachments above a few megabytes; keeping individual photos around 500 KB is a reliable way to stay well within typical attachment limits, especially when sending several photos in one email.
If your goal is faster page loads rather than a form requirement, consider WebP output here — it typically produces noticeably smaller files than JPG at the same visual quality, so a 500 KB WebP often looks better than a 500 KB JPG of the same photo.
Usually not by much — 500 KB is large enough that most consumer photos need only mild compression to reach it, so quality loss is typically subtle.
Often yes for the same visual quality, WebP files tend to be smaller — but check that wherever you're uploading to actually accepts WebP before switching.
Yes, add up to 100 images at once; they process one by one with a progress bar and download together as a ZIP.
Re-encoding through Canvas does not preserve embedded EXIF metadata (including GPS location), so compressed images are also a simple way to strip that data if privacy is a concern.
