Reduce image size in KB, resize photos and convert PNG to JPG. Works offline
Shrink photos, reduce image size in KB, convert HEIC to JPG and resize pictures in bulk – right on your phone. Your photos are never uploaded anywhere.
Photo too large to upload? Attachment over the email limit? Stuck with iPhone photos you can't open? ImageFlow is a photo compressor, image resizer and image converter that keeps it simple: choose what you want to do, pick your photos, and get smaller copies in seconds. Your originals stay exactly as they are.
📉 COMPRESS PHOTOS
• Three compression levels: Light, Balanced and Maximum.
• Compress without losing visible quality on Light, or go fully lossless with PNG or lossless WebP (PRO).
• Compress images to 100 KB, 500 KB or 1 MB.
• See exactly how much space you saved, with a before-and-after slider and zoom.
🔄 CONVERT IMAGE FORMATS
• HEIC to JPG: turn iPhone photos from email, cloud storage or your computer into JPEGs that open anywhere.
• PNG to JPG, JPG to PNG, WebP to JPG, AVIF to JPG – or any mix of JPG, PNG and WebP.
• Supports JPG, PNG, WebP, HEIC, HEIF, AVIF, GIF and BMP.
• Save as JPG, PNG, WebP or HEIC (on supported phones).
• Transparent backgrounds get filled with the color of your choice.
📐 RESIZE IMAGES
• Resize by the longest side (1024, 1280, 1920, 2048 or 3000 px) or by percentage.
• Lower the resolution without stretching: aspect ratio is always kept, and small photos are never upscaled.
⚡ BATCH PROCESSING
• Compress, convert and resize several photos at once: up to 5 per batch for free, unlimited with PRO.
• Full optimization handles format, dimensions and file size in one go.
• One-tap presets for email, websites and online forms.
• Works with the Share menu: share photos from any app to ImageFlow, then send the smaller versions right back to the chat.
🔒 PRIVATE BY DESIGN
• Everything is processed on your device, and it works offline.
• No account, no sign-up, and no access to your whole gallery – only the photos you choose.
• Strip the GPS location before you share a photo.
• Your originals are never modified: ImageFlow always saves a new copy.
