Compressing Photos With Text for DSLR Photos

Updated April 6, 2026 · 7 min read

Text inside photos, like signs or slides, needs a gentler touch. Camera JPEGs straight off the card can be many megabytes each, which is heavy for sharing or web use.

Recommended settings for DSLR photos

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 3000 px on the long edge
Quality85
File size1000 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Compressing Photos With Text

JPEG tends to create faint ringing around sharp letter edges. Keep quality around 80 to 85 and avoid shrinking below the size at which the text is readable.

If the image is mostly text, consider PNG. For DSLR photos, test a quick compression and zoom in on the lettering before you upload.
