Image Resizer: frequently asked questions
Answers to the questions people ask most before resizing images.
How many images can I resize at once?
Up to 50 images in one batch. Each original is previewed immediately after upload, so you can check what you selected before resizing.
Which image formats are supported?
You can upload JPG, PNG or WebP images, and choose JPEG, PNG or WebP as the output format for the resized copies.
How do I stop an image from looking stretched?
Keep the Keep aspect ratio option checked, so the height adjusts automatically when you change the width. Only turn it off when you need a specific stretched size.
What is the difference between custom dimensions and percentage?
Custom dimensions set the same target width and height in pixels, while percentage mode scales every image from its own original dimensions, so images of different sizes stay proportionally different.
Are my images uploaded to a server?
No. Your images are resized locally in your browser, so they are not sent to Tools2030.
