Frequently Asked Questions

What is an image resizer?

An image resizer changes the pixel width and height of a photo or graphic, either to make it smaller for faster loading or larger for a specific use like a banner or thumbnail.

How do I resize an image without losing quality?

Resize down rather than up whenever possible, keep “Lock Aspect Ratio” checked so the picture doesn't stretch, and export as PNG or high-quality JPG/WebP to avoid extra compression artifacts.

Can I resize JPG images online?

Yes — upload a JPG using the tool above, set your new width and height, and export. JPG is one of the default supported output formats.

Can I resize PNG images?

Yes, PNG is fully supported, including images with transparent backgrounds, which are preserved when you export as PNG or WebP.

Can I resize multiple images at once?

Yes — use the Bulk Resize tool to upload several images, apply the same width, height or percentage to all of them, and download them individually or as a single ZIP file.

Is the image resizer free?

Yes, resizing images with ImageToolPro is completely free, with no sign-up required.

What image formats are supported?

You can upload JPG, PNG, WebP, GIF, BMP and HEIC files (HEIC support depends on your browser), and export as JPG, PNG, WebP or BMP.
