Frequently Asked Questions
Is ResizeLab really free?

No. All resizing happens directly in your browser using the Canvas API. Your images never leave your device.
What image formats are supported?
You can upload JPG, PNG, or WEBP images, and export to any of those three formats.
Will resizing reduce my image quality?
Resizing to smaller dimensions generally preserves visual quality well. For JPEG/WEBP you can also control the quality/compression slider to balance file size and clarity.
