Image Resize
Full instructions and common questions
Image Resize
Set pixel width and height, preserve the original aspect ratio or choose new proportions, then preview the output.
How to use
- Upload an image or try the sample and check its original dimensions.
- With aspect ratio locked, change one dimension. Unlock to set both dimensions independently, which can stretch the image.
- Choose a format, process the image and inspect the preview before downloading.
Try an example
The sample is 1200 × 800 pixels. Keep the aspect ratio and set width to 600. Height becomes 400 and the exported image is 600 × 400 pixels.
Limits and privacy
Inputs up to 30 MB and outputs up to 40 million pixels. Enlarging cannot restore detail missing from the original. JPEG does not preserve transparency.
Common questions
How can I avoid stretching?
Keep aspect ratio enabled. To change the composition, crop first and resize afterwards.
Does editing dimensions download immediately?
No. Process and preview first, then download when satisfied.
