Batch Compressing Photos for Event Flyers
When you have dozens of images, consistency matters as much as size. Flyers get forwarded through chats and email, and a lighter file travels further without friction.
Recommended settings for event flyers
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 300 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Batch Compressing Photos
Drop all the files at once. The same settings are applied to each, so a set of photos for event flyers ends up with matching dimensions and similar file sizes.
Use Download all to collect everything in one ZIP. A target of 300 KB per image keeps the whole batch predictable.
