Frequently Asked Questions

What image formats can I resize?: You can resize PNG, JPG, JPEG, WebP, and BMP images. Output can be saved as PNG (lossless), JPEG (compressed), or WebP (modern format with best quality-to-size ratio).
Does resizing reduce image quality?: Quality depends on your settings. PNG is lossless and preserves all detail. JPEG and WebP use a quality slider (0-100%) — higher values mean better quality but larger file sizes. We recommend 80-90% for web use.
Is there a file size limit?: There is no file size limit imposed by us. However, very large images may use more memory in your browser. The tool processes images locally, so performance depends on your device.
