On this page you can find some information on the file formats used in IMSLP. If you want to download the PDF file of the score you're currently looking for, you clicked the wrong link. Please go back and click on the score description to retrieve the PDF.

These are the only file formats IMSLP accepts for scores. Raw image files, whether loose or ZIPped, will be removed.
Portable Document Format (PDF) is the main type of document used here on IMSLP for music scores. To view PDF files, download one of the recommended clients:
For Ubuntu users who browse the web with Firefox, click here to install Mozplugger. Mozplugger embeds the Evince PDF Reader (among other things) inside Firefox. Evince is installed by default, but you can make sure by clicking here.
For Mac (OS X) users, creating PDF files is possible without additional software. A tutorial can be found here.
Note: Mac users should not use Preview to open pdf files. Preview is not able to display some of the files on IMSLP correctly.
IMSLP allows users to upload the source files (.sib, .mus, .ly, etc.) of their own typesets. All of the relevant files should be archived in a single ZIP. Each source file must also be uploaded separately in PDF format. Isolated ZIP files will not be accepted, nor will loose notation files. Note that this is the only permitted use of the ZIP format.
To extract files from a ZIP file, you can use one of the following applications:
Note, also, that in the latest version of most known operating systems (Windows, Linux, Macintosh) there are pre-installed applications with which you can open ZIP files (Windows XP and up have WinZip installed, in Linux there is Ark and 7-Zip etc).

Codecs information
FLAC stands for Free Lossless Audio Codec. As it is lossless, there is no loss of audio fidelity during conversion to and from this format, unlike in formats such as Ogg Vorbis and MP3. However, it tends to take up more space. FLAC provides compression levels from L0 (little to no compression) to L8 (maximum compression). All of these compression levels are lossless, but the higher compression levels use more CPU to encode and slightly more to decode in order to represent the exact same data in less space.
MP3 stands for MPEG Audio Layer III. It is a lossy format that supports various different bitrate settings. MP3 compression is available in a variety of different flavors, including CBR (constant bit rate), VBR (variable bit rate), and ABR (average bit rate). In MP3 CBR encoding, audio is represented in a user-defined bitrate. Because the bit rate does not change at all in CBR, less complex parts are inefficiently encoded with higher bitrates. Common bitrates (in kilobits per second) for CBR include 96, 128, 160, 192, 256, and 320. On the other hand, in MP3 VBR encoding, audio is represented using a quality setting. The encoder uses this quality setting to determine different bitrate settings for parts of audio files rather than entire audio files, so complex parts get higher bitrates and less complex parts get lower bitrates.
OGG stands for Ogg Vorbis. Ogg Vorbis is very similar to MP3, but it uses variable bitrate encoding. It uses different internal techniques to encode audio.
MP4 is a container format that can contain audio, video, and other streams. It is often used to store videos, but can also be used to store only audio. Typically, audio in MP4 containers is encoded in AAC or MP3.
MIDI is a file format that can store musical sequences. When played back, the sequences are read by the computer, which creates a synthesized performance of the music within the MIDI file.
Notes
Raw PNG and JPG images can be uploaded using Special:Upload, found in the 'toolbox' section in the left sidebar. The following are accepted uses for these formats:
DJVU is a file format very similar to PDF, and is conceived as a replacement for PDF. DJVU is especially designed for scanned documents, so the document legibility is higher than PDF at the same file size. Detailed information can be found here.
Some applications that can view/create DJVU files:
File formats used by Finale and Score. The code is not interchangeable between the two programmes.
Finale MUS files can be read and printed using the free Finale Reader.
MUS files cannot be uploaded directly, but instead should be archived in a ZIP file (see above)
File format used by Sibelius. SIB files can be read/printed after installing the free Scorch plugin.
SIB files cannot be uploaded directly, but instead should be archived in a ZIP file (see above)
