Where can I get free sound effects for my game?
Three kinds of free, and only one is safe to ship without reading further. What to check before downloading, which free sources are worth using, and when free stops being worth your time.
- Free with attribution, free for personal use, and free for commercial use are three different licences
- Free tiers usually hand out MP3; the engine wants WAV

Where can I get free sound effects for my game?
You can ship a whole game on free sound effects, as long as you read the licence before you download rather than after. "Free" covers three different deals: free with attribution, free for personal use only, and free for commercial use with no conditions. Only the last one can be dropped into a game you sell without further thought. The other two are perfectly usable; they just come with a line in your credits or a limit on what the project can be.
What should I check before I download a free sound?
Three things. Can you use it commercially? Do you have to credit the author, and where? And what format is it in? A free MP3 is fine for prototyping, but Unity and Unreal re-encode audio on import, so an already-compressed file is compressed twice, and on short transient sounds that is audible. WAV is the format to ship; the format guide explains why.
Which free sources are worth using?
ZapSplat. ZapSplat describes its library as over 160,000 free sound effects downloads, 750+ SFX packs and more than 1000 royalty-free music tracks. Under its Standard License, a free account may use the sounds in an unlimited number of personal, commercial and broadcast projects, games included, but free users get MP3 only, are subject to download limits, and must credit "ZapSplat" wherever reasonably possible, for example in end credits or documentation. Its premium tier, billed monthly or yearly, adds WAV, removes the attribution requirement, and sounds downloaded while the subscription is active stay attribution-free for life. The premium price is shown once you have an account, so it is not quoted here.
The Sonniss GameAudioGDC archive. Each year Sonniss gives away a bundle of professional sound effects to mark the Game Developers Conference, and the archive holds ten years of them, from GDC 2015 to GDC 2024. Sonniss states that all of the sounds are royalty free and commercially usable, that no attribution is required, and that they may be used on an unlimited number of projects for life. The licence covers media production, meaning games, film, TV and interactive projects, and forbids use for AI training. The bundles are large, so download the collections you need rather than everything.
Outta This World Audio free packs. 387 free sounds across 46 downloads, all 44.1 kHz 16-bit WAV levelled to −1.5 dBTP, licensed for commercial use with no attribution. They are genre samplers, so each covers the sounds a particular kind of game needs rather than a little of everything, and the 33-sound sampler is a direct ZIP with no account or email required.
When does free stop being worth it?
When you spend longer searching than building. Large free libraries are wide but uneven, and matching the loudness and tone of sounds from many different authors takes real time; the loudness guide covers why per-file normalisation makes that worse. At that point either a subscription, such as ZapSplat's premium tier or Envato Elements, which bundles sound effects and music with video templates, graphics and fonts, or a themed pack that was made as one matched set is cheaper than your hours. The subscription or packs guide compares the two routes.
If you want one set that already matches, the Complete Game SFX Library is 1007 sounds across 32 packs for a one-time price. Try the 387 free sounds first; they are made to the same standard.
