Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

  • Start from the original image whenever possible.
  • Review the output before publishing or deleting your original file.
  • Use related tools like resize, convert or metadata removal when you need a more specific result.
  • Choose the right format for the job: JPEG for photos, PNG for sharp graphics and WebP for modern websites.

Bringing big photos under 1 MB

Email providers, forums, support ticket systems and document portals often draw the line at 1 MB per image. It is a generous budget: a 12 megapixel photo typically lands under 1 MB at quality 80 or higher, which is visually indistinguishable from the original on any screen. The usual culprits above the line are DSLR files and screenshots saved as giant PNGs.

ImageFits under 1 MB?
Phone photo, 12 MPYes, at near original quality
DSLR photo, 24 to 45 MPYes, the tool finds the quality automatically
Huge PNG screenshotYes, JPG or WebP output converts it under the limit
Tip: Sending several photos by email? Compress them all here first, then attach. Five photos at 900 KB each beats five rejected sends at 4 MB each.

Other size targets

If the limit is tighter, the presets at 200 KB and 500 KB have you covered, and Compress Image to Size accepts any number, including 2 MB or 5 MB for bigger ceilings.
