PureMIDI

PureMIDI is a browser music toolkit for turning sound and scores into editable MIDI, then continuing the work without installing a DAW. Producers, musicians, and learners upload a source, and the converter estimates pitch and timing so the result can be exported as a standard MIDI draft. You can start with audio, or choose video, sheet music, an existing MIDI file, or an authorized YouTube workflow. A free preview is available before sign-in, and no credit card is required to try the preview.
Choose whether the audio is one melody or a full song. A single melody covers a vocal line, a guitar riff, a bass line, or a solo instrument. A full song contains drums, chords, and several instruments at once. Supported audio formats include MP3, WAV, M4A, FLAC, OGG, WEBM, AAC, and AIFF. The upload limit shown on the converter is 25 MB. Video workflows accept local files such as MP4, MOV, WebM, or M4V and convert the audio track. Sheet-music workflows, marked beta, accept MusicXML and MXL, plus photographed or scanned score images and PDFs through AI score recognition.
The MIDI editor runs in the browser. You can draw notes, edit more than one track, play the result back, and export MIDI. A MIDI file can also be opened as readable notation, played, and edited further. Guitar Pro tablature can be converted to standard multi-track MIDI locally in the browser, and MIDI can be mapped back to playable standard-tuning tab and exported as a validated Guitar Pro 7 file. Separate guides compare the browser workflow with Ableton, Logic, FL Studio, and REAPER, so the MIDI can be dragged back into the DAW you already use. Instrument pages cover piano and guitar recordings, including electric, acoustic, and DI guitar.
The basic path has four steps. Upload a source such as an MP3, WAV, M4A, or sheet-music PDF. Choose one melody or a full song and review the credit cost before a full conversion. The system estimates pitch, timing, and structure, then prepares an editable MIDI file. Download that file and refine it in a DAW or notation program, or keep editing it in the browser. Output is a standard .mid file that opens in Logic Pro, Ableton Live, FL Studio, Cubase, Reaper, GarageBand, Studio One, Pro Tools, MuseScore, Sibelius, Dorico, and other major tools.
Credits are one-time packs rather than a subscription. A short free preview, up to about thirty seconds for eligible audio, is available before sign-in. Video and score conversion require an account. Only a successful conversion uses credits. The site says uploaded audio and scores are not used to train models. Producer pages also include an eight-bit music generator and an instrumental maker that splits a song into stems and can convert a stem to MIDI. Planned tools such as an AI MIDI generator and text-to-MIDI are labeled as waitlist items, so they are not presented as finished features. Support is by email at support@puremidi.com.
