Start with a clean square original and keep the important features near the center. Each service may resize or mask that file after upload, so its current upload screen is the final check.
Official guidance checked on 2026-08-09
| Service | Current published guidance | Practical check | | --- | --- | --- | | X | 400 by 400 recommended; JPEG, GIF, or PNG; up to 2 MB | Inspect the circular profile crop. | | LinkedIn | 400 by 400 through 7680 by 4320; PNG or JPG; up to 8 MB | Keep the face centered in the crop tool. | | YouTube | JPG, GIF, BMP, or PNG; no animated GIF; up to 15 MB; rendered at 98 by 98 | Check the channel icon after saving. | | Discord | PNG and GIF avatars are documented; no single pixel dimension is published | Use the current profile editor and member-list view. | | TikTok | The app provides a crop step; published guidance can vary by help locale | Judge the current in-app crop. | | WeChat | No stable official public pixel requirement was found | Follow the current in-app picker and crop. |
The table does not invent a number where the service does not publish one. Requirements and display behavior can change.
These figures are not interchangeable. X publishes a recommended upload dimension, LinkedIn publishes an accepted range, and YouTube describes the rendered profile image. Discord documents formats without one required pixel size. Keep those meanings separate instead of turning every number into a universal canvas requirement.
Use a crop-safe source
Build and save a square image in Square PFP. Keep eyes, mouth, and the main hair shape away from the corners. Upload the original rather than repeatedly resizing and resaving it.
After upload, check both the crop screen and the smallest placement you use. A file can satisfy the upload form and still be hard to recognize in a comment or member list.
If a 256px generator export is accepted, enlarging it smoothly to 400px does not create new detail. Keep the native file. For a service or professional use that genuinely needs a larger source, recreate the design from a higher-resolution original rather than presenting an upscale as higher-quality artwork.

Final upload checklist
- Keep the original square PNG.
- Center the recognizable feature.
- Preview the service's circular or rounded crop.
- Inspect a small real placement after saving.
- Recheck the official upload screen when these limits matter.
