JPEG, PNG, WebP, AVIF, HEIC. All processing stays in your browser.
The 500KB limit is common for email systems with attachment recommendations, social profile photo uploads and general web platform image requirements. At 500KB, images retain full visual quality in nearly all cases.
Email attachment compression
Many email clients recommend keeping individual image attachments under 500KB to avoid delivery issues.
Social media profile photos
LinkedIn, professional networks and some social platforms cap profile and header images at 500KB.
Cloud storage and sharing platforms
Some cloud storage services and shared drive systems impose a 500KB limit on embedded or shared images.
Website and blog image uploads
CMS platforms and blog systems may enforce a 500KB upload limit on images through their media manager.
500KB is enough space to store an excellent quality photograph at typical web display resolutions. The limit is common on platforms that want to prevent very large unoptimised uploads while still allowing high quality images.
Compressing a phone photo to 500KB almost always produces a result that is visually identical to the original at screen viewing sizes. 500KB is a very generous target for most photographs.
JPEG, PNG, WebP, AVIF and HEIC are all supported as input. The output is JPEG or WebP depending on your selection. JPEG is the safest choice for submission portals as it is universally accepted.
No. All compression happens entirely in your browser. Your image never leaves your device. You can verify this by disconnecting from the internet after the page loads, the tool still works.
