HOW TO CONVERT ICO → DPX
Provide the ICO
Click or drag to upload. We accept a single ICO file per job, with an optional queue of additional images for batch mode.
Encode to DPX
The conversion decodes the ICO, resolves the colour space to sRGB and writes the DPX container around the pixel data.
Save the DPX
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all DPX outputs is produced instead.
ICO is the Windows icon container with multiple resolutions packed into one file. Reaching a DPX from there is one hop. Turn a ICO image into a DPX in seconds. The two formats share the same raster DNA so the visible quality is very close; what changes is how the file is packaged, which matters for browsers, editors and CMS uploaders. KaijuConverter runs the conversion server-side and deletes both files within two hours. Technical note: ICO is the Windows icon container with multiple resolutions packed into one file. Compare that with DPX is a raster image format with its own balance of compression, colour depth, and software support.
Why convert ICO to DPX
The real reason to move from ICO to DPX is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking DPX solves those edge cases at the cost of a short conversion step.

ICO vs DPX — Strengths and limitations
What each format does best, and where it falls short.
ICO Strengths
- Multi-resolution: one file, many sizes, OS picks the right one.
- Universal favicon support in every browser since IE5.
- Supports transparency (1-bit since 1985, full alpha since XP).
- Tiny file size — an entire favicon pack typically fits in under 15 KB.
- No licensing or patent concerns — fully in the public domain spec-wise.
Limitations
- Cannot compress continuous-tone images efficiently — use PNG or WebP for photos.
- Format is essentially frozen in 1999 — no HDR, no wide gamut, no modern features.
- Maximum image dimension is 256×256 px (inside an ICO container).
DPX Strengths
- Industry-standard archival format for film.
- Logarithmic color encoding preserves film look.
- Lossless — no generation degradation.
- SMPTE standardized (SMPTE 268M).
- Every VFX and color-grading app reads and writes DPX.
Limitations
- No compression — file sizes are enormous.
- Not a display format — requires color-managed pipelines.
- Gradually superseded by OpenEXR in modern VFX.
Quality & Compatibility
ICO-to-DPX conversion does not change the visible content. Quality is capped by the ICO decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original ICO alongside the DPX copy.
Tips for Best Results
- Large ICO files may look identical to small DPX files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export DPX at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related ICO images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both ICO and DPX are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If DPX is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded ICO exactly, but cannot recover detail that ICO had already compressed away.
Often yes, especially when DPX is lossless. ICO tuned for efficient web delivery will usually produce smaller files than DPX's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
ICO Icon
Source formatICO is the icon file format used for favicons and Windows application icons. A single ICO file can contain multiple image sizes and color depths for different display contexts.
Digital Moving-Picture
Target formatDPX (Digital Picture Exchange) is a SMPTE standard file format for digital intermediate and visual effects work. It stores per-frame image data with rich metadata for color management and is widely used in film post-production pipelines.

Common Use Cases
Share across platforms
Send DPX files to anyone without worrying about whether they have the right software for ICO.
Embed in documents
Drop DPX output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
DPX often produces smaller files than ICO for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
