Terms of Service

The rules for using Sheet Music to MIDI: accounts, page credits, plans and renewals, cancellation and refunds, what you may upload, and our responsibilities.

Last updated: November 13, 2026

These terms are an agreement between you and Sheet Music to MIDI ("we", "us"), the operator of Sheet Music to MIDI at sheetmusictomidi.net (the "service"). By creating an account or using the service, you agree to them. If you don't agree, please don't use the service.

The service

Sheet Music to MIDI is an online service delivered through your browser. We may add, change or remove features over time.

The service reads the notes on sheet music you upload and creates MIDI and MusicXML files and a playable preview. Recognition is automatic and can contain mistakes, especially with handwritten music, tablature, small print or poor photos, so check the results before you rely on them.

Your account

You must be at least 18, or the age of majority where you live, to use the service. Give accurate information, keep your sign-in details safe, and tell us right away at support@sheetmusictomidi.net if someone else uses your account. One person per account: don't create several accounts to collect extra free credits.

Credits

  • One credit converts one page. The number of pages and credits is shown before you start. If a page fails to convert, its credit is returned. Pages blocked by our content checks are not charged.
  • Plans add their credits once a month; yearly plans add them monthly over the year. Plan credits expire at the end of the month they were added for.
  • Credit packs are one-time purchases. Their credits expire 12 months after purchase.
  • Free credits for new accounts are limited each day, go to one account per person and network, and expire 30 days after they are added. Throwaway email addresses don't receive them.
  • When you have credits from several sources, the ones that expire first are used first. Credits have no cash value and can't be transferred or exchanged for money.
  • When a payment is refunded or disputed, the credits it added are taken back.

Plans and payments

  • Plans and prices are listed on our pricing page: each plan's price, whether it is billed monthly or yearly, and what it includes. Prices are in US dollars. Sales tax or VAT is added at checkout where it applies.
  • Automatic renewal. A plan renews automatically at the end of each billing period, at the price shown at checkout, until you cancel. By subscribing, you authorize the charge for each period to your payment method.
  • Credit packs are one-time charges, authorized at checkout.
  • Upgrades start right away at the full price of the new plan, and a new billing period starts that day. Yearly plans can't be changed until the year ends; to move to a smaller plan, cancel and subscribe again when your period ends.
  • Who sells your order. Checkout is handled by Stripe, our online reseller and merchant of record. It is the seller of record for your purchase, collects any sales tax, and also handles order-related inquiries and returns. The charge on your statement shows its name or ours.
  • Your card details are entered on the checkout page of Stripe. We never see or store your full card number.

Cancellation

You can cancel a plan at any time in your account: open Billing and choose Manage. Cancellation takes effect at the end of the period you have paid for: you keep your plan and its credits until then, and you are not charged again. Credit packs you bought separately are not affected.

Refunds

If something went wrong with a charge, such as a duplicate charge or a charge after you canceled, tell us at support@sheetmusictomidi.net within 14 days and we will refund it. Because your credits and plan are ready to use as soon as you pay, we can't offer refunds when you simply change your mind, except where the law gives you that right. You can cancel a plan at any time so that it doesn't renew. When a payment is refunded, what it paid for ends: the plan stops, and the credits the payment added are taken back.

Billing problems

If you believe a charge is wrong, please contact us at support@sheetmusictomidi.net before disputing it with your bank. We reply within 2 business days and correct confirmed billing errors within 5 business days.

Acceptable use

Use the service only for lawful purposes. Don't:

  • break any law, or infringe anyone's copyright, trademark, privacy or other rights;
  • harass, threaten, defame or impersonate anyone;
  • create or share content that sexualizes minors, or violent, hateful or illegal content;
  • try to get around our limits or content checks, gain unauthorized access, or disrupt the service;
  • use the service through scripts or automated tools, or resell access to it, without our written permission.

What you upload

  • You keep all rights you have in the music you upload. You give us permission to process it only to provide the service to you.
  • Only upload sheet music you have the right to use, such as public-domain music, your own work, or music you are licensed to copy for your own practice or production. You are responsible for what you upload.
  • We do not publish, share or sell your uploads or results. They are visible only in your account and are deleted on the schedule in our Privacy Policy.
  • If you believe someone used the service to infringe your copyright, email support@sheetmusictomidi.net and we will look into it.

Suspension and termination

We may suspend or close your account if you break these terms, if we suspect fraud or abuse, or if the law requires it. If we close your account for a reason other than a breach of these terms, we will refund the unused part of any prepaid period. You can stop using the service and delete your account at any time in your account settings.

No warranties

The service is provided "as is" and "as available". We don't promise that it will always be available or error-free, or that every result will match what you had in mind.

Limit of liability

To the extent the law allows, we are not liable for indirect, incidental or consequential damages, or for lost profits or data. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim, or $50 if you paid nothing. Some places don't allow these limits, so they may not apply to you.

Open-source software

The score display and playback in your browser use open-source libraries, including Verovio (LGPL-3.0, source at github.com/rism-digital/verovio) and Tone.js (MIT). They are used unmodified and stay under their own licenses; these terms do not limit your rights under them.

Changes

We may update these terms. If a change is meaningful, we will update the date above and tell you by email or on the site before it takes effect. Continuing to use the service after that means you accept the new terms.

Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region, except where the law of your country gives you rights that can't be waived. Before any formal dispute, please contact us so we can try to resolve it.
