Frequently Asked Questions

TurnPic supports conversion to and from WebP, AVIF, PNG, JPG, GIF, BMP, SVG, and ICO. You can convert any supported source format to any supported output format. Each converter page lists the specific source formats it accepts.

Lossy compression (JPG, WebP lossy, AVIF lossy) discards some image data to achieve much smaller file sizes, with a slight reduction in visual quality. Lossless compression (PNG, WebP lossless) preserves every pixel exactly but produces larger files. Choose lossy for web photos where file size matters, and lossless for images where perfect quality is essential.

For most websites in 2026, WebP is the best default choice - it offers excellent compression and is supported by over 97% of browsers. If you need the absolute smallest files, use AVIF. For images requiring transparency, use WebP or PNG. For maximum compatibility (e.g., email), use JPEG.

Yes, TurnPic supports batch conversion. You can upload up to 30 images in a single batch, and each image can be up to 10 MB in size. After conversion, you can download each file individually or all at once as a ZIP archive.

This depends on the output format and quality setting. Lossless formats (PNG, BMP) preserve all image data. Lossy formats (JPG, WebP, AVIF) allow you to control the quality level - higher settings preserve more detail while lower settings produce smaller files. At quality 80 or above, most users cannot distinguish the converted image from the original.

Yes. All images are transferred over HTTPS and are used only to perform the requested conversion. TurnPic does not sell, share, or use your images for any purpose other than the conversion you requested. Files are not used to train machine-learning models.

Uploaded and converted files are automatically removed after 24 hours. An automated cleanup task runs every hour to delete files that are older than 24 hours. You should download your converted files promptly after processing.

Yes. All image conversion and editing tools on TurnPic are completely free to use with no subscription, no hidden fees, and no usage limits. The service is supported by advertising to cover hosting and maintenance costs.

Each image file can be up to 10 MB in size. If your file exceeds this limit, please compress or resize it before uploading. You can use TurnPic's resize tool to reduce image dimensions before conversion.

You can upload up to 30 images in a single batch. If you need to convert more than 30 images, simply process them in multiple batches.

Yes. TurnPic offers a background removal tool that automatically detects and removes the background from your images, producing a transparent PNG. This is useful for product photos, portraits, and any image where you need a transparent background.

Yes. TurnPic includes a resize tool that lets you adjust image dimensions by percentage or by specifying exact width and height. The tool maintains aspect ratio by default and supports proportional scaling.

ICO is a specialized format for icons, primarily used for website favicons (the small icons in browser tabs) and Windows application icons. TurnPic generates ICO files with multiple sizes (16x16, 32x32, 48x48, 256x256) in a single file.
