FAQ

What resize methods does the tool support?
It supports exact pixel resizing (width×height) and percentage scaling, with aspect ratio locked by default to prevent distortion. You can upscale or downscale while keeping the original format.
How do I resize an image to exactly 1080×1080?
Upload, enter 1080 for width — height scales automatically. If the source is not square, unlock the ratio first and enter 1080×1080 manually; the tool crops or stretches to fit.
Does upscaling make images blurry?
Upscaling stretches pixels and softens detail. The tool uses high-quality smooth resampling, better than plain browser zoom. Prefer original high-res images; downscaling is lossless.
Does resizing affect image quality?
Downscaling is usually visually lossless; upscaling adds slight softness. Output uses high-quality resampling with 95% JPEG quality, ready for web, e-commerce and social sizes.
Is online resizing safe?
Safe. Processing happens locally in your browser; images never reach a server, suitable for unpublished drafts, business assets and personal photos.
Which platform sizes does it cover?
Xiaohongshu (3:4/1:1), Taobao main images (800×800/1000×1000), WeChat cover (900×383), avatars (1:1) and more — export and use directly.
Are there limits on free resizing?
No. Free, no registration, unlimited, supporting JPG/PNG/WebP for e-commerce, media and office workloads.
Can I scale by percentage?
Yes. Percentage mode takes an input like 50% and scales both dimensions proportionally, handy for quick thumbnails and previews.
