How to Reduce Image File Size (Without Wrecking Quality)
“Your file is too large.” Whether it’s an email limit, a slow-loading website, or an upload that just won’t go through, an oversized image is a common headache — and an easy fix.
Why images get so big
Modern phone cameras produce enormous files. Most uses — email, web, social media — don’t need that full size, so compressing trades a little invisible detail for a much smaller file.

- For email and web, a moderate quality setting usually cuts size dramatically with no visible change.
- For print, keep quality higher to preserve detail.
- Still too big? Also reduce the dimensions — see how to resize an image.
Compress and resize together
Compression lowers quality; resizing reduces the pixel dimensions. For the smallest possible file, do both.
Frequently asked questions

- Which format compresses best?
- JPG and WEBP are best for photos; PNG is better for graphics but compresses less.
