Highlights
Feature Comparison
Features Overview
We highlight the main differences and pick a winner for each feature.
Video Volume & Limits
HeyGen offers unlimited videos monthly; Synthesia severely caps output by generated minutes.
HeyGen’s Creator and Team plans allow users to generate unlimited videos for a fixed monthly rate. While HeyGen videos are capped at 30 minutes long, you never worry about overage charges. Synthesia uses a credit system, limiting its Starter and Creator plans to just 10 or 30 total minutes per month. If you exceed Synthesia’s minute limit, video generation stops immediately until your next billing cycle. If you need high, predictable content volume, HeyGen is the superior choice for your workflow.
Avatar Realism
HeyGen is praised for hyper-realistic avatars, often surpassing Synthesia’s corporate look.
HeyGen invested heavily in its Avatar IV technology, leading to exceptionally lifelike digital duplicates. Users frequently report HeyGen’s avatars are virtually indistinguishable from real people in video tests. Synthesia’s avatars are high-quality and professional, prioritizing corporate consistency. However, they are occasionally seen by users as slightly less dynamically expressive than HeyGen’s options. If achieving the highest possible visual realism is key, HeyGen holds a slight but noticeable edge in the market.
Security and Governance
Synthesia offers superior enterprise compliance, including required SSO and ISO42001 certification.
HeyGen meets baseline compliance standards like GDPR, CCPA, and SOC 2 TYPE II certification. Synthesia is purpose-built for enterprise use and adheres to stricter standards, adding ISO42001 certification. Synthesia’s Enterprise plan includes advanced authentication features like SAML/SSO access, a must-have for large organizations. When legal or procurement teams are scrutinizing compliance, Synthesia provides a more robust security profile. Synthesia is trusted by CFOs for its governance structure.
LMS Integration
Synthesia excels at integrating content workflow into existing corporate Learning Management Systems.
Synthesia provides crucial functionality for L&D teams by supporting SCORM export for LMS integration. When you edit a Synthesia source video, its built-in version control automatically syncs the updates without creating duplicates. HeyGen does not explicitly list SCORM export or automatic versioning control in its feature set. For organizations managing complex internal training libraries, Synthesia’s system features save significant management time. Synthesia simplifies distribution and compliance training updates.
Localization Detail
HeyGen translates into more languages and meticulously preserves the original speaker's voice and tone.
HeyGen offers superior global reach, supporting instant translation into over 175 languages and dialects. When translating, HeyGen’s AI preserves the original speaker's unique voice, tone, and pacing during the conversion. Synthesia supports 140+ languages and offers AI Dubbing, which ensures accurate lip-syncing for professional results. While both localize well, HeyGen’s commitment to retaining tonal integrity gives it massive speed advantages. HeyGen’s feature set is perfect for branding where speaker identity is important.
Video Quality Export
HeyGen offers the highest potential export quality with 4K resolution, while Synthesia is standard 1080p.
HeyGen provides 4K video export resolution exclusively on its paid Team plans, suitable for large displays. The HeyGen Creator plan still offers high-quality 1080p export resolution. Synthesia’s standard plans typically export content in 1080p quality for professional use. If raw visual spec is your main concern, HeyGen gives you the ability to produce maximum fidelity assets. Synthesia focuses less on 4K resolution and more on corporate asset quality.
Our Verdict
The decision between HeyGen and Synthesia boils down to volume versus governance priorities. Synthesia is the established favorite for large corporations, but HeyGen offers more speed and cutting-edge tech. Ultimately, Synthesia holds a higher user satisfaction rating, suggesting better platform reliability. HeyGen’s superpower is making hyper-realistic video production cheap and incredibly plentiful. Paid plans offer unlimited videos monthly, avoiding the annoying minute caps imposed by Synthesia. HeyGen also supports 175+ languages and exports in stunning 4K resolution, perfect for external marketing campaigns. If you are a high-volume creator and need raw output, HeyGen delivers better value. Synthesia's strength lies in security, structure, and reliable corporate deployment. They offer SOC 2 Type II and ISO42001 compliance, which legal teams genuinely appreciate. Synthesia also integrates videos seamlessly into existing Learning Management Systems using SCORM export. If you produce internal training or compliance videos, Synthesia provides essential system governance. The critical deciding factor is your video volume combined with your infrastructure needs. If you need to publish 50+ videos monthly without tracking usage minutes, HeyGen offers far more affordable scalability. If your L&D team needs secure SSO and reliable LMS integration, you must invest in Synthesia. Choose HeyGen if you prioritize predictable monthly pricing and superior avatar realism. Choose Synthesia if strict corporate security, proven platform reliability, and system integration are non-negotiable requirements.
