Convert HEIC to JPG, save photos as PNG or PDF, and create WebP or AVIF images for the web. Image Converter & Compressor lets you batch convert photos and images on your iPhone. Select images from your photo library or Files, then choose an output format. Keep your images in a consistent format or adjust the balance between image quality and file size. 8 OUTPUT FORMATS Convert images to JPEG (JPG), PNG, HEIC, WebP, AVIF, GIF, TIFF, or PDF. • Convert HEIC photos to JPEG (JPG) for sharing or uploading to services that require JPG. • Export photos and screenshots as PNG. • Create WebP and AVIF images for websites and blogs. • Save as HEIC, TIFF, or a still GIF to suit your needs. • Turn photos and images into PDF files to share. GIF output is a still image. Creating or preserving GIF animation is not supported. PDF conversion creates a separate file for each image. ADJUST QUALITY AND COMPRESS IMAGES JPEG, HEIC, WebP, and AVIF support quality settings. The free version converts at an 85% quality setting. Pro lets you adjust quality from 10% to 100%. Choose a higher setting to prioritize image quality, or a lower setting to reduce file size for email attachments and web use. The percentage is an encoding quality setting. Even 100% does not guarantee identical quality to the original. Output file size varies by image and format. Quality adjustment is not available for PNG, GIF, TIFF, or PDF. BATCH CONVERSION Select multiple images from your photo library or Files and convert them to the same format in one batch. Track the number of images being processed as conversion progresses. PREVIEW, SAVE, AND SHARE Preview converted images before saving or sharing. Share or delete multiple converted files at once. When saving to your photo library, you can also choose an album or create a new one. Save PDFs to Files or another destination using the share menu.
