PICON to JPG Converter
A .picon file came out of an old mail or news program, or from an image tool's export, and you cannot see what it shows. PICON is a tiny thumbnail format stored as text, close to XPM. This converter reads it on your device and saves a picture you can open or enlarge.

Free to use on any site. Paste the code where you want the tool to appear. It runs inside the page; visitors' files are processed in their own browser and are not uploaded.
WordPress and most site builders have a "Custom HTML" block where this code can be pasted. The embed keeps a small link back to CalcMaster.
How to convert PICON to JPG
- Add your PICON files by dropping them, clicking the drop zone or pasting.
- The output format is already set to JPG. Adjust quality or size if you need to.
- Press Convert and compare the original and new size for each file.
- Download each file or all of them as a ZIP.
When to convert, and when not to
- You found face or icon thumbnails from an older mail or news program and want to view them.
- An image tool exported a .picon preview and you want a normal copy.
- A website or editor rejects the .picon extension.
- Do not expect detail: these thumbnails are small by design.
What changes
- The text is read with the same colour-table logic used for XPM files.
- Colour names and hex values are both understood, and None means transparent.
- Transparent areas are filled with your background colour when you save as JPG.
- The picture is small, so enlarge it with Resize, accepting visible square pixels.
- Only the picture is kept; names and comments in the file are ignored.
What a PICON file is
The name comes from personal icon. These files were small thumbnails used to put a face or an emblem next to a person or a topic, for example beside the sender of a message. They are written as text, in a layout very close to XPM: a short header, a table of colours and rows of characters that stand for the pixels.
You are unlikely to meet a PICON in daily life any more, which is why no ordinary viewer supports it. The converter fills that gap by decoding the text with its XPM reader.
Small pictures and how to enlarge them
A personal icon was made to sit in a corner of a window, so the whole picture may be only a few dozen pixels across. Opened at its real size on a modern screen it looks like a postage stamp.
Use the Resize option with a percentage to make it larger. The tool repeats each pixel as a bigger block rather than inventing detail, so the picture stays blocky. That is the faithful result and often fine for recognising a face or a logo.
Transparency and output choice
Many icons have transparent corners so that they fit any background. JPG cannot store transparency, so those parts are filled with the background colour you pick, white by default. If you would like to keep them see-through, choose PNG or WebP as the output.
If the file contains a colour name that the built-in X11 colour list does not know, or the rows are shorter than the header claims, the converter reports an error instead of drawing a wrong picture. You can then check the file in a text editor.
Because PICON files are so small, a whole folder of them converts in moments. Add them together, check the thumbnails in the queue and download the lot as a ZIP, keeping the original files as they are.
Privacy: your files stay on your device
- The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
- To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.
Frequently asked questions
What does PICON stand for?
Personal icon. The files are small thumbnails used to show a face or emblem beside a name or topic.
How is it related to XPM?
Both are text-based colour pictures with a colour table. The converter uses the same reader for both.
Why is my result so tiny?
The original is a small thumbnail. Enlarge it with the Resize option; expect visible blocks.
Will transparent parts stay transparent?
Not in JPG, where they take your background colour. Choose PNG or WebP to keep them.
Why do I see a colour error?
The file names a colour that is not in the built-in list. Replace it with a hex value in a text editor.
Can I convert a whole folder of PICON files?
Yes. Add them together, convert them in one run and download the results as a ZIP. Your original files are not changed.
