Compress any photo to an EXACT file size โ€” type 200 KB and get 200 KB, on the first try. Email limits, web forms, visa applications, listing portals, forum avatars โ€” they all want a photo "under X KB". Image Compressor hits that number precisely instead of guessing with a quality slider, so you never upload, fail, and retry again. HOW IT WORKS โ€ข Pick photos from your library or the Files app. โ€ข Type your target โ€” 50 KB to 4 MB, or tap a preset. โ€ข Tap Compress. A smart multi-pass search lands your photo just under the target at the best possible quality. โ€ข Compare before and after with a slider, then save or share. WHY IMAGE COMPRESSOR? โ€ข Exact-KB targeting โ€” not a vague low / medium / high slider. โ€ข Before/after comparison โ€” check every pixel before you send. โ€ข 100% on-device โ€” your photos never leave your iPhone. No uploads, no servers, no account. โ€ข No ads. Ever. โ€ข Batch mode โ€” up to 20 photos to one target in a single run (Premium). โ€ข Metadata removal โ€” strip EXIF and GPS location before sharing (Premium). โ€ข JPEG or HEIC output (Premium). โ€ข Savings history โ€” see how many megabytes you reclaimed this week. โ€ข Fully localized in 38 languages. FREE VS PREMIUM The free version includes 3 exact-size compressions per day with the full before/after preview. IMAGE COMPRESSOR PREMIUM Premium unlocks unlimited compressions, batch mode, metadata removal, and HEIC output. Premium is available as a weekly auto-renewable subscription with a 3-day free trial, or as a one-time Lifetime purchase. Subscriptions auto-renew until canceled. Cancel anytime in your Apple ID Subscriptions settings at least 24 hours before the renewal date.
