Match dimensions to the destination
Image resizing changes pixel dimensions, file-size limits, or both. Choosing a specific goal prevents oversized uploads, distorted images, and avoidable quality loss.
Review the settings and result rather than relying on a single default for every image.
Exact dimensions
Use width and height when a website, marketplace, form, or social platform requires a specific pixel size.
Percentage scaling
Use a percentage when you want a proportional version without calculating new dimensions manually.
Target file size
Use a KB or MB target when an upload form enforces a file-size limit. The result may also reduce dimensions to meet that limit.
Which resize mode should you use?
Fixed slots, thumbnails, banners
Keep aspect ratio unless stretching is intentional
Quick proportional reduction
Values above 100% enlarge but cannot create new detail
Forms, portals, email limits
Smaller limits require a quality or dimension tradeoff
Common web and social sizes
Confirm the destination’s latest requirements
Quality-check your result
A short review helps prevent blurred text, lost transparency, unexpected dimensions, or an output that is larger than necessary.
Clear processing expectationsThe selected file is processed to create the requested output. Results depend on the source image and chosen settings. Keep important originals and review the site’s privacy policy for handling details.
Keep aspect ratio enabled to avoid distortion.
Avoid enlarging small sources unless necessary.
Review both pixel dimensions and file size in the results.
Retain the original for future crops or higher-resolution exports.
