Frequently Asked Questions

Do these image tools upload my files to a server?

No. Every tool on this page processes your images entirely in your browser using the Canvas API. Your files never leave your device — not even for a fraction of a second. No files are logged, stored, or transmitted anywhere.

What image formats are supported?

The tools support JPEG, PNG, WebP, GIF, and SVG depending on the tool. The most common formats (JPEG and PNG) are supported by all tools. WebP input is supported in Chrome, Edge, and Firefox. HEIC/HEIF (iPhone format) is not currently supported.

Is there a file size limit for images?

There is no hard limit — the practical limit is determined by your browser's available memory. Files up to 20–30 MB work well on most modern devices. For very large images, closing other browser tabs frees up memory.

Do the processed images lose quality?

It depends on the tool and settings. Lossless tools (PNG conversion, resizing) preserve full quality. Compression tools offer a quality slider — higher quality = larger file, lower quality = smaller file. The original file is never modified; you always receive a new output file.
