How Should You Compress Images for a WeChat Article?
Most WeChat public account articles are read on a phone with a limited screen width, so images don't need to keep the original resolution of a desktop screenshot or a DSLR photo — but compressing too aggressively will blur text-heavy images like screenshots and diagrams.
A phone screen doesn't need desktop resolution
When an article image renders on a phone, the actual display width rarely exceeds the screen's physical width (typically around 1080-1290px on mainstream phones). If the source is a desktop screenshot (often 2560px wide or more) or a straight-out-of-camera DSLR photo (often 4000px+), it far exceeds what's actually needed for display — the only effect is a larger article and slower load, with no visible quality benefit.
Suggested settings by image type
| Image type | Suggested preset | Suggested longest side |
|---|---|---|
| Product / lifestyle photos | Balanced | 1200-1600px |
| Screenshots / UI images with small text | High quality | Around 1600px, to avoid blurring text |
| Cover / header image | Balanced or high quality | ~900px wide (matching the platform cover ratio) |
| Purely decorative images / dividers | Max compression | Whatever size it actually displays at |
Batch-processing every image in one article
A long article often has a dozen or more images. Put them all in one folder, drop the whole batch into the tool with a shared compression strength and max-side setting, then download the ZIP and insert them into the editor in order.
- Pull text-heavy screenshots out and process them separately at a higher quality setting, so they don't get over-compressed along with everything else.
- Preview the article on an actual phone before publishing to confirm text in key screenshots is still readable.
