Frequently Asked Questions
Does resizing reduce quality?
Downscaling (making smaller) preserves quality well. Upscaling beyond original size causes blurring — always start with a high-resolution original.
Common sizes for social media?
Profile picture: 400×400px. Facebook cover: 820×312px. YouTube thumbnail: 1280×720px. Instagram post: 1080×1080px.
Can I resize multiple images at once?
The resizer processes one image at a time. Use the Image Compressor for batch processing.
Is there a size limit?
No hard limit. Very large images (30MP+) may be slow in some browsers. Chrome and Edge handle large files best.
Will resizing change the format?
Only if you choose a different output format. You can convert format during resize — e.g. upload PNG, download WebP.
