Image Tools

JPG uses lossy compression and is usually practical for photographs without transparency. PNG is lossless and preserves alpha transparency, which suits interface graphics, screenshots and logos but can produce larger files. WebP supports lossy or lossless images, transparency and animation, while AVIF can be efficient for modern delivery. HEIC is common for phone photos, especially from Apple devices, but is less consistently accepted by websites and desktop software.

Resizing changes pixel width and height. Compression changes how those pixels are encoded and can trade detail for a smaller file. Cropping changes the visible frame, while conversion changes the output format and its available features. A smaller file can come from one or several of these operations, so compare both dimensions and visual quality rather than relying on file size alone.

JPG has no alpha channel, so a transparent input needs an explicit background. A static conversion may preserve only one frame of an animated source; the relevant converter states that limitation before processing. Browser-created outputs also do not promise to retain every camera, location or editing metadata field. Keep the original when that information matters.

UtilSprout decodes and exports selected images in the browser instead of uploading them to a conversion service. Large dimensions and batches still consume local memory, so each tool applies practical file, pixel or batch limits. Close other memory-heavy tabs or process fewer files together if a phone or older computer struggles.
