Convert image files with our easy-to-use and free tool. Our tool lets you upload a PNG (Portable Network Graphics) file and, from this, create a new image saved in the TXT (Data URI Scheme) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple PNG image files; up to 25 files at a time can be converted.
Along with converting PNG image files to TXT, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available within the Options tab. Along with grayscale, you can also mirror or flip the image if needed. For single PNG file uploads, you will also see options to resize and rotate your image.
This option can be used to rotate the image in 90° increments.
When selected, this option will flip the image vertically.
When selected, this option will mirror the image horizontally.
When checked, this will apply a grayscale filter to the image, turning any color image into a grayscale image.
When checked, this will apply a negative filter to the image, inverting all the colors within the image.

The PNG graphics file format is a commonly used format for storing 2D images, which can be highly compressed by the use of a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.
PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990s as a superior format to GIF. PNG files are generally used for company logos, icons, and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image, hence the PNG format being unsuitable for most digital photo content.

The Data Uri TXT file format is a method of embedding external webpage resources, such as images, directly into the HTML markup. The benefit of embedding external resources is that it reduces HTTP requests for a webpage, thus reducing the overall load time.
Data is encoded using the Base64 method of encoding binary data as text using ASCII characters. Due to the encoding method, the resulting file size will be around 33% larger than the binary equivalent, so there is a trade-off between the number of HTTP requests and the increase in request size.
First click the "Upload..." button, select your PNG file to upload. Select any configuration options. When the PNG to TXT conversion has completed, you can download your TXT file straight away.
We aim to process all PNG to TXT conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the PNG file you submit to us. The resulting TXT file, once created is deleted 20 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your PNG file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted TXT file quickly.
Yes! Our PNG to TXT tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our PNG conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your PNG to TXT, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
