Downsizer: Photo Resizer

Welcome to Downsizer 1.0 — resize photos in pixels, percent, cm or inches, preview the compressed file size live, and save in JPEG, HEIC or PNG. Downsizer makes photos smaller — in dimensions, in file size, or both. Pick a photo, choose a size, set the quality, and save. That's it. RESIZE ANY WAY YOU THINK • Pixels for screens and websites • Percent for quick scaling (one-tap 25%, 50%, 75% presets) • Centimeters or inches for print, with adjustable DPI (72–600) • Aspect-ratio lock keeps photos in proportion — or unlock it for exact dimensions SEE THE FILE SIZE BEFORE YOU SAVE The compression preview shows the actual output file size as you adjust quality — not an estimate. Watch a 4 MB photo become 300 KB and know exactly what you'll get. CHOOSE YOUR FORMAT • JPEG — universal compatibility • HEIC — smallest files, ideal for iPhone • PNG — lossless, perfect for graphics and screenshots SAVE OR SHARE Save straight to your photo library, or share the resized file to Mail, Messages, Files, AirDrop, and more. PRIVATE BY DESIGN Everything happens on your iPhone. Downsizer collects no data, shows no ads, requires no account, and never sends your photos anywhere. Perfect for: • Emailing photos that are "too large to send" • Meeting upload size limits on forms and websites • Preparing images for the web at exact pixel dimensions • Sizing photos for print at the right DPI • Freeing up storage by shrinking screenshots and scans
