TIFF Won't Open? Convert to JP2 Instantly
Fast, instant TIFF to JPEG 2000 conversion. No signup required. Just drop your .tiff file and get .jp2 in seconds.
Batch Settings
HDR data will be tone-mapped
Your TIFF file may contain HDR (High Dynamic Range) data. JP2 only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Layers will be flattened
TIFF supports multiple layers, but JP2 does not. All layers will be merged into a single flat image. Keep your original TIFF file if you need to edit individual layers later.
Some metadata may not survive
Your TIFF file may contain IPTC, XMP metadata. JP2 has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
CMYK → RGB color conversion
Your TIFF file uses CMYK color space (designed for print). JP2 uses RGB. Colors will be converted — some print-specific colors (especially deep blues and vivid oranges) may shift slightly. For critical color matching, use a calibrated ICC profile.
Color depth reduction: 32-bit → 16-bit
TIFF stores up to 32 bits per channel, but JP2 supports only 16 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
TIFF形式の画像は、その高い品質と柔軟性から、特に印刷やアーカイブ分野で長年重宝されてきました。しかし、ウェブでの表示速度やストレージ効率を考えると、より現代的なフォーマットへの変換が求められる場面も少なくありません。そこで注目されるのが、優れた圧縮率と画質維持を両立させるJPEG 2000（JP2）です。この変換は単なるファイル形式の変更に留まらず、デジタルコンテンツの取り扱いをより快適で効率的なものへと進化させます。特に、繊細な表現が求められるイラストや、情報密度が高いビジネス文書において、JP2の特性は大いにその真価を発揮するでしょう。本ページでは、TIFFファイルをJP2に変換する手順とその利点について詳しくご紹介します。
- 漫画・イラストのウェブ公開
- ビジネス文書の軽量化と共有
- 高精細な古文書デジタルアーカイブ
日本の漫画や古文書のスキャンデータなど、縦書きや独特の線の表現が多いコンテンツでは、JP2の非可逆圧縮におけるアーティファクトの少なさが特に評価される傾向にあります。また、フォントのディテール維持にも優れています。
About TIFF to JPEG 2000 Conversion
Dealing with a TIFF file that won't open on your device? You're not alone — TIFF compatibility issues are one of the most common reasons people search for a file converter. TIFF is an uncompressed or losslessly compressed format favoured in print, publishing, and professional photography.
The fix is simple: convert your TIFF to JP2. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate. This conversion lets you convert between formats quickly, solving the problem in seconds rather than hours of troubleshooting.
Full Name: TIFF uses Tagged Image File Format, while JP2 uses JPEG 2000. Compression: TIFF uses Lossy & Lossless, while JP2 uses Lossy & Lossless. Transparency: TIFF uses Yes, while JP2 uses Yes. Your TIFF file may contain HDR (High Dynamic Range) data. JP2 only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
CocoConvert processes your TIFF file on secure servers in Germany — upload, convert, download. Your files are encrypted via TLS and automatically deleted within 24 hours. No account needed, no software to install, and it works on any device with a browser.
This conversion is ideal when you When you specifically need a JP2 file for your workflow.
The conversion engine behind CocoConvert uses FFmpeg, Sharp, and qpdf — the same open-source libraries trusted by Netflix, YouTube, and enterprise platforms. Pro users can batch convert up to 100 files at once.
How to Convert TIFF to JPEG 2000
- 1
Add your TIFF file
Drag and drop your .tiff file into the converter, or tap "Browse" to pick it from your device. Multiple files are supported for batch processing.
- 2
Pick JP2 output
Select .jp2 as the target format. CocoConvert automatically applies the best quality settings for this conversion.
- 3
Start conversion
Hit the Convert button. The image engine processes your file server-side — no CPU drain on your device.
- 4
Save your file
Once done, download your .jp2 file. For batch jobs, download all at once as a zip.
What Happens When You Convert TIFF to JPEG 2000
Your TIFF image is decoded into raw pixel data, then re-encoded as JP2.
Your TIFF file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using JPEG 2000's lossless compression
Metadata (EXIF, ICC profiles) is transferred where JP2 supports it
The JP2 file is saved and ready for download

Should You Convert TIFF to JPEG 2000?
When to Convert
- ✓When you specifically need a JP2 file for your workflow
When NOT to Convert
- ✗You still need to edit individual layers — JP2 flattens everything
- ✗You want to preserve HDR information — JP2 only supports standard dynamic range
Frequently Asked Questions
Why won't my TIFF file open?
TIFF files may not open if your device lacks the right codec or application. Converting to JP2 — a more widely supported format — usually resolves this. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate.
Is it safe to convert TIFF to JP2 online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting TIFF to JP2?
Your TIFF file may contain HDR (High Dynamic Range) data. JP2 only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my TIFF file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert TIFF to JP2 on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
