## Kompressor Description
Kompressor (a compressor with a K!) is a powerful yet simple image converter for your iPhone and iPad. Convert your photos — RAW files from your iPhone or DSLR camera*, or standard lossy images already in your library — into compressed JPEG or HEIC formats while maintaining control over quality, size, and metadata.

REQUIREMENT: You need existing photos in your Photo Library to convert. Kompressor does not capture photos — it converts the image files you already have.

KEY FEATURES:

Convert up to 25 images at once
Support for both RAW and standard (JPEG, HEIC, PNG) input formats
Support for JPEG and HEIC output formats
Adjustable compression levels (50%, 75%, 95%)
Flexible image resizing options
Complete control over metadata preservation
Detailed metadata options including EXIF, GPS, TIFF, and more
Device-specific metadata support (Apple, Canon, Nikon, Fuji, Olympus, Pentax, Minolta)
Comprehensive compression statistics and charts
Preview converted images before saving
Clean, intuitive interface
100% offline processing - no data collection
Support for iPhone and iPad
METADATA CONTROL: Kompressor gives you granular control over which metadata to preserve:

Image Depth & Orientation
EXIF, GPS, and TIFF metadata
IPTC information
Camera manufacturer-specific data
DNG metadata
Custom creation date options
COMPRESSION OPTIONS: Choose from three quality levels:

50% - Maximum compression for space savings
75% - Balanced quality and size
95% - Near-original quality with significant size reduction
RESIZING OPTIONS: Reduce image dimensions while maintaining aspect ratio:

50% - Half the original size
75% - Three-quarters of original size
100% - Keep original dimensions
PRIVACY FIRST: All processing happens directly on your device. No analytics, no tracking, no cloud processing. Your photos stay completely private.

PERFORMANCE: Optimized for modern iOS devices with support for the latest iPhone and iPad models. The app limits batch conversions to 25 images to ensure optimal performance.

Perfect for photographers who want to:

Free up storage space by converting RAW or JPEG files
Re-compress existing photos to smaller sizes
Share photos in more compatible formats
Control file sizes for uploads
Manage photo metadata
Convert images without complex desktop software
Made with love in Toronto

* Digital Negative (DNG) file

Note: Photo library access is required to convert images.

## Kompressor Reviews in United States

### *---- "Stopped working"
Used to be great, but stopped working with the major update. Now it always shows me the same small selection of photos, no matter how many I give it permission to access.
-- metamatic, 2026-01-20

### *---- "Rebuilt App removes old functionality entirely"
I loved the old Kompressor app because it let me compress any image. The new app only allows RAW compression. Some of my HEIC images might be 3MB and before I could easily bulk shrink them to under 1MB. This is now impossible.
-- Kcalkompi, 2026-01-15

### ***** "Excellent app!"
I’ve had this app for several years and it works great!  Does exactly what it says it does. Even after compressing and then making changes to photo, you can compress again. It May not be much but every little bit helps!!  It’s never bugged out or glitched on me. Very reliable!! Thank you!!!
-- Tga5843, 2022-07-21

### ***** "Really Convinient"
No ads or anything, no sign up, just straight up decompression. I wish you could decompress videos though.
-- Joshua Duehring, 2021-10-04

### ****- "Video compressor"
Hi i need one apps same with this kompressor but fir video to save and replace my recorded video
-- vb1619, 2020-03-18

### ***** "آفرین"
ادم لذت میبره از یه همچین کارایی 
خدا قوت رفیق
-- Ehsanshafie, 2019-10-20

### ****- "Good first try"
I kinda like it, it addresses an important need.  Changes I would like is to make the compression function stand-alone, I don't want or need yet another filter generator, there are hundreds of filter apps already.  Also would like a variable slider not just 3 presets. Finally (and this is the dealbreaker) PLEASE add a "save-as" or "save-copy" so it doesn't replace my original with a compressed version.  That ruins it for me.
-- toddhunt, 2019-05-29

### *---- "Doesn’t work"
After installing then deleting, twice the same thing happens on the iPad Pro. 2 screens FLASH back and forth without being able to sit up the application, much less the app show in the app list. Doesn’t appear anywhere on the iPad Pro. What gives?
-- mac70graphics, 2019-05-29

### ***** "Very Impressed!"
This app does exactly what it says, with no loss in image quality.  I routinely process/edit 15-24mp DSLR images on my iPad Pro. I took a 16.2 mp image that weighed in at 7.8mb and “Kompressed” it at the highest setting to 1.3MB, still retaining the 16.2mp image resolution.  Since this app works as an extension, I copied the Kompressed image, then Reverted the original back to its un-Kompressed state. I then loaded them both into TwinViewer and zoomed in to 400% and could not tell the difference in the two images. Absolutely no change in resolution, no artifacts, nothing different.  I use JPEGMini on my PC and it delivers similar results, this is truly a breakthru for iOS users. I am suitably impressed.

Recommended improvements to the app would include running as a standalone app that could batch process a bunch of images. As an extension, it would be nice if there was a Copy function/option so you could duplicate the Kompressed image without having to use a different extension app.
-- Techno-nut, 2019-04-30

### *---- "Takes too long"
It takes an eternity to compress a simple picture although I have iPhone Xs Max 512! It happens to all images.
-- Great-Phoenix, 2018-12-15

### ****- "iMessage your photos faster and easier"
Although iOS10 provides an option to send a compressed version of a photo in the Messages app, I'm just wondering why the implemented feature is not as practical as what this app offers. Unlike the built-in feature, you can simply reduce the size of your photos with a single tap without sacrificing the quality so much.

I hope it shows bigger image preview panes in portrait mode.

### ***** "thanks"
very thanks
-- imana41, 2015-10-16

### ***** "perfect ......"
perfect app . . . . . .
