Frequently asked questions
Common questions about the Image Resizer.
How does Image Resizer work?
Upload a JPG, PNG, or WebP image (up to 20 MB). Set exact pixel dimensions or a percentage scale, optionally lock aspect ratio, then resize. ToolsArk redraws the image in your browser and keeps the original format.
Does my image leave my device?
No. Resizing runs in your browser. ToolsArk does not upload your image to a server.
Can I change the file format while resizing?
No. This tool keeps the original format. Use Image Converter if you need a different format, or Image Compressor if you mainly want a smaller file.
What are the presets for?
Presets fill common social and media sizes (for example Instagram, YouTube, and LinkedIn dimensions). You can still edit width and height afterward.
Will quality change?
Yes. The tool re-encodes through canvas (about quality 92 for lossy formats), so file size and fine detail can change even when dimensions change only slightly. JPEG output replaces transparency with white.
