Image Resizer
Resize JPEG, PNG, and WebP images to custom dimensions or percentages. Lock proportions, use presets, preview, and process batches.
Resize images to custom dimensions
Set a width, height, or percentage and keep the original aspect ratio by default. Common web dimensions are available as presets. Turn off aspect-ratio locking when you explicitly want both dimensions stretched. Batch processing applies the same dimensions to each image; the original orientation is read from browser-decoded pixels.
Frequently asked questions
How do I resize without stretching?
Keep the aspect-ratio option checked. If you enter both width and height, the image is fitted inside those dimensions without distortion.
Can I resize several images at once?
Yes. Select a batch and the same dimensions or percentage are applied to each image.
What do the presets mean?
The presets set common pixel bounds such as 1280 × 720. With aspect ratio locked, the output fits within those bounds while preserving the source proportions.
Does resizing upload my image?
No. The browser performs decoding and resizing locally.
