Frequently Asked Questions
- Does resizing an image reduce its file size?
- Yes. Reducing pixel dimensions reduces file size proportionally — a 50% resize typically reduces file size by around 75%. For further reduction, use JPG or WebP format with a lower quality setting.
- How do I resize an image without losing quality?
- Use PNG format when resizing — it is lossless and preserves every pixel. For JPG or WebP, set quality to 85% or above to minimize visible compression artifacts.
- Is my image uploaded to a server?
- No. All image processing happens entirely in your browser using the Canvas API. Your image never leaves your device and is never uploaded to any server.
- What image formats are supported?
- You can upload JPG, PNG, WebP, and GIF images (up to 10 MB). Output can be downloaded as JPG, PNG, or WebP.
