Supports: ODD
Turn an ODD file into a clean PNG image. Drop your file in, pick a quality preset, and download a lossless PNG with full transparency support — no sign-up and no watermark. The .odd extension is used by several unrelated programs (voice-recorder data, game data, and various legacy image tools), so if your file opens as a picture, this is the tool to render it out to a standard PNG that every browser and image editor reads.
PNG is the right target when you need crisp edges or transparency; JPG wins only when the source is a photograph and file size matters more than a perfect copy.
| Property | PNG (this tool) | JPG |
|---|---|---|
| Compression | Lossless (DEFLATE) | Lossy |
| Transparency | Yes (alpha channel) | No |
| Best for | Logos, screenshots, line art, sharp text | Photographs, large color gradients |
| Re-saving | No quality loss on repeated edits | Degrades each save |
| Typical file size | Larger | Smaller |
| Color depth | 1–16 bits per channel, indexed/grey/truecolor | 8 bits per channel |
Need a smaller file from a photo-like image instead? Use the ODD to JPG converter, or convert the finished PNG with PNG to JPG.
If your source image carries an alpha channel, PNG can preserve it — PNG supports full alpha-channel transparency. If the original has no transparency, the PNG simply renders on an opaque background; nothing is added or removed.
The PNG itself is lossless — it uses DEFLATE compression, the same algorithm family as ZIP, so no pixel data is discarded. The Quality Preset and Compression level control how hard the encoder works to shrink the file, not how much detail is thrown away. In our testing, raising the preset to "Very High" produced a slightly larger file than "Medium" with byte-for-byte identical pixels.
PNG stores every pixel exactly with lossless compression, so for detailed or photographic content the output is often bigger than a compressed source. To shrink it, lower the palette under Colors (for example to 256 indexed colors), reduce the resolution, or convert to JPG instead when transparency is not needed.
The .odd extension is shared by several unrelated formats, including audio and game-data files that are not pictures. This converter only handles ODD files that contain image data. If your file is audio or document data, an image converter cannot render it — open it in the program that created it first.
Files are uploaded over an encrypted connection and processed on our servers — never shared or made public. Uploaded files and their outputs are deleted automatically a few hours after conversion, and there is no sign-up or watermark.
