## What is Fast Image Viewer Free?

A powerful image viewer built from the ground up with highly optimized code especially adept at viewing large bitonal images (e.g. engineering drawings, well logs, etc). Unlike competing products, FIV does not require importing images to local storage and does not need to create any temporary data on your device. It can access images in your camera roll and all supported cloud storage services and open them directly with no delays. Fully functional and no in-app purchases.

*** Now with 3D-Touch support - Quick Actions, Peek/Pop and accelerated pressure-sensitive image panning

The paid version allows printing and converting images to PDF then emailing them. The free version displays a full page ad before opening each file.

FIV can view the following image formats:
TIFF (TIF) - single or multiple pages, (Uncompressed, Packbits, LZW, JPEG, Huffman, G31D, G32D, G4, Flate/ZIP, Planar, CMYK, RGB, YCbCr)
BMP (Windows, OS/2, RLE)
DICOM (uncompressed, RLE, JPEG, animated)
CALS (type 1)
JEDMICS C4 (US Military images)
GIF (+Animated)
FLI/FLC (Animated)
PNG (+Animated)
PGM/PBM/PPM
JPEG (baseline, progressive, extended, lossless, YCbCr, RGB, CMYK, YCCK)
JPEG2000 (jp2/j2k/dicom/pdf)
PCX,DCX (multipage PCX)
Targa (uncompressed, RLE)
QuickLinks FAX
Microsoft FAX (*.AWD)
WinFAX
BitFAX
FITS (astronomy images)
PDF - NOTE: PDF support is limited to scanned images such as FAXes, NOT text or vector graphics. This is useful if you know your PDF file contains scanned images because FIV can view and navigate it much quicker than other PDF viewers.

FIV is great at viewing large black & white scanned images. Unique technology allows for incredibly fast decoding and readable scale-to-gray (anti-aliased) views. Navigate between pages/files in milliseconds even on less powerful phones.
FIV is capable of viewing well logs faster than any other software available. As an oil/gas/water well log viewer, FIV can open scans up to 600 x 600 inches (@400dpi).

### 1/5 — Ads Ads Ads

*2025-05-30, version 2.0.2*

Yeah i do understand that the app is free. But showing an ad EACH TIME i open a file is a bit too much. Not recommended to anyone who values their sanity.

### 4/5 — Можно улучшить

*2021-03-04, version 2.0.2*

Было бы хорошо, если бы настраивалась или убиралась информация о странице. Например я листаю ноты и меня отвлекает информация «страница 3»
Это не такая важная информация, чтобы ею так экран перекрывать, можно перенести в строку состояния куда-то в уголок. Спасибо

### 5/5 — Good app

*2020-01-28, version 2.0.2*

This app is pretty good. 5-star

### 1/5 — Doesn’t Work

*2019-09-19, version 2.0.2*

Can’t open TIFF files from google drive as advertised. Fortunately I hadn’t upgraded to the paid version before trying. Useless for my needs.

### 2/5 — Bummer...

*2018-11-18, version 2.0.2*

Had hope it would let me see images on an SD card from my camera. But no... doesn’t even read the card, which is probably Apples fault. 🙁

### 2/5 — Перебор с рекламой

*2017-10-26, version 2.0.2*

Я конечно понимаю, что программа бесплатна, но не через каждые же 5 секунд рекламу показывать!

### 5/5 — Hap

*2016-05-24, version 2.0.1*

Great App!
Accomplished my task exactly as I needed in less than a minute!
Highly recommend!

### 5/5 — единственная бесплатная понимает tif

*2016-04-19, version 2.0.0*

можно просматривать многостраничные tif, конкуренты только 1 страницу видят

### 5/5 — The fastest way to view TIFF files

*2016-02-16, version 2.0.0*

For any tech support questions, please send an email before writing a review.

### 1/5 — Wouldn't work for me

*2016-02-15*

I'm not sure who this app is designed for, but I tried to add a simple .jpg file and FIV rejected it with an unhelpful message ' "Documents" is read only and cannot be modified. ' Aside from the grammatical error, the information is unhelpful. The .jpegs I experimented with are not protected, and load perfectly into other IOS apps.
I admit that I wasn't able to experiment any further, but the problem was big enough, and their error message was worse than useless, so I feel it has earned the One-Star "I hate it" rating.

**Developer response:** This error message did not originate in FIV. To open any supported image file, use the share icon from the owning application or open FIV and access files from the camera roll or cloud file services directly.
