Convert a Whole Folder of Images at Once

Key takeaways

• Why convert images in batch — Someone sends you fifty photos as PNG files and you need every one as JPG.
• How to convert a whole folder at once — step by step — Open the Batch Convert tool from the image tools.
• Which formats you can convert to — The tool writes JPG, PNG, WebP, TIFF and AVIF — the formats that cover phones, forms, websites and print.
• JPG, PNG, WebP, AVIF or TIFF — which should you pick? — JPG for sharing and for forms: everything opens it.
• Keep the look, lose the weight — Conversion never changes your image's dimensions — a 3000 × 4000 photo stays 3000 × 4000.
• Fast zero-retention batch processing — Files are deleted the moment you leave the page, reload, or replace them.
• Honest limits worth knowing — Batch conversion runs on our processing server — your files travel over an encrypted connection, are converted, and are deleted the moment you leave the page, so download your set before you close the tab.
• Frequently asked questions — The questions people actually search for, answered straight.
• How do I convert many images to JPG at once? — Open Batch Convert, add the whole set, choose JPG as the output format, press convert and download the finished set.
• Does batch converting reduce image quality? — The dimensions never change.
• Are my photos private when I batch convert? — Yes.
• Which is the smallest format for a website? — Usually WebP — the same picture for roughly a third less weight than JPG, and every modern browser opens it.
