Free online TIFF to MID converter

What the TIFF format is

TIFF (Tagged Image File Format) is a raster image format commonly used for scanned sheet music, archival scores, and high-resolution page images. Scanners and applications such as Adobe Photoshop, GIMP, and professional document-imaging software create TIFF files. TIFF can preserve lossless detail, multiple pages, grayscale data, and high resolutions, but it does not contain playable notes or an editable musical structure.

What the MID format is

MID is a filename extension for a Standard MIDI File. It stores musical instructions including note numbers, start times, durations, channels, tempo changes, controller data, and program changes; it does not store recorded sound. MIDI files are useful for playback through synthesizers, editing in notation and digital audio workstation software, changing instruments, and producing smaller files than audio recordings.

How to actually convert TIFF to MID

For printed or handwritten notation, use optical music recognition rather than a normal image converter. A practical desktop workflow is Audiveris followed by MuseScore:

1. Prepare the score as a clear TIFF at approximately 300–600 dpi. Crop empty borders, straighten tilted pages, and remove speckles; separate pages if the recognition software handles only one page at a time.
2. Open Audiveris and choose File → Open, then select the TIFF image.
3. Run the recognition process and inspect the detected staves, clefs, key signatures, time signatures, tuplets, and note durations. Correct recognition errors before exporting.
4. Export the result from Audiveris as MusicXML, using .xml or compressed .mxl as the output format.
5. Open the MusicXML file in MuseScore with File → Open. Compare every measure with the source TIFF, then correct pitches, rhythms, voices, articulations, and page breaks.
6. Export the MIDI file through File → Export, choose MIDI as the format, and save it with a .mid extension. Select the required MIDI type and track layout if MuseScore presents those options.

You can also try the free converter on 101convert.com without installing software. A service must include music-notation recognition to produce useful MIDI; a basic raster-format conversion only changes the file container or image encoding and cannot create notes from a score.

Quality and compatibility limits

Recognition accuracy depends on clean notation, adequate resolution, regular engraving, and unambiguous separation of voices. Complex rhythms, grace notes, handwritten scores, lyrics, guitar tablature, orchestral systems, damaged scans, and overlapping symbols commonly require manual correction.

TIFF pages containing only artwork, a cover, or an audio waveform cannot be converted into meaningful MIDI notes. MIDI also cannot preserve the original page appearance, fonts, lyrics layout, print spacing, or every notation marking. Keep the TIFF and corrected MusicXML as archival sources, because the exported MID contains playback data rather than a complete visual score.

Different MIDI players may interpret tempo, instrument programs, percussion mappings, dynamics, and articulation controls differently. Test the exported file in the intended sequencer, notation program, or hardware device and adjust the MIDI channel and instrument assignments when necessary.
