Frequently Asked Questions

How does the image resizer work?▾
The resizer uses the HTML Canvas API to redraw your image at the specified dimensions. All processing happens entirely in your browser — no images are uploaded to any server.
Which output formats are supported?▾
You can export resized images as PNG (lossless), JPEG (lossy with adjustable quality), or WebP (modern format with excellent compression). Choose the format that best fits your needs.
Does resizing reduce image quality?▾
Downscaling generally preserves quality well. Upscaling beyond the original resolution may introduce some blurriness. For JPEG and WebP, you can adjust the quality slider to balance file size and visual fidelity.
