Frequently Asked Questions
Where are the ads on this image resizer?
There are none. That is intentional. As an IT solutions company, we fund our operations through enterprise client work, not ad placements. This image resizer runs entirely in your browser, so we do not pay server costs to process your files. We built this tool as a free utility for the community, without needing to monetize your attention or data.
Do my uploaded images leave my device?
No. Your files never leave your device. This image resizer processes everything locally in your browser using client-side JavaScript and the Canvas API. No uploads. No server transfers. No cloud storage. We have no access to your files, no tracking pixels, and no cookies. Your privacy is structurally guaranteed by how the tool is built.
Does resizing reduce image quality?
Making an image smaller generally preserves its crispness. Enlarging an image past its original dimensions will cause pixelation. We recommend only scaling down for the best results. Use the quality slider to fine-tune the output balance between file size and visual fidelity.
What image formats are supported?
This tool supports PNG, JPG (JPEG), WEBP, and AVIF formats. You can mix and match these formats in a single batch. Each format has specific advantages. PNG preserves transparency. JPG produces smaller files for photographs. WEBP offers the best compression for web use. AVIF provides next-generation compression.
Can I batch resize multiple images at once?
Yes. Upload multiple files, set your target dimensions, and download all resized images packaged as a ZIP file. The ZIP mode is ideal for processing entire folders of photos in one click. Each image is resized individually to your exact specifications.
