Frequently Asked Questions (FAQs):
What is the best free online image resizer for desktop and mobile?
FreeConvertio offers the best pixel-perfect on-device Image Resizer. It lets you scale pictures using custom pixel dimensions (width & height in px) or by percentage scaling directly inside your browser cache. Zero files are uploaded to third-party databases, making it the safest option for proprietary work.
Does resizing images affect the original visual file quality?
Our resizer tool uses optimized HTML5 Canvas canvas resampling techniques to preserve maximum sharpness of your JPG, PNG, and WebP frames. You can also crop or adjust dimensions with our accompanying Image Cropper tool.
How can I batch-resize multiple images at the same time?
Simply drag and drop multiple images into the input upload area. FreeConvertio executes the resizing loop sequentially on your machine and triggers automatic local downloads, so you can resize hundreds of files instantly.
