Bulk Subtitle Translation for $3: Meet SubDL Plus and Pro

Subtitle translation is usually priced like a specialist tool, even when all you need is a clean subtitle file in another language. SubDL Plus and SubDL Pro take a simpler approach: low monthly pricing, useful translation allowances, and a workflow made for movie and TV subtitle files.

The newest part of that workflow is private bulk subtitle translation. Instead of uploading one episode at a time, you can bring a complete folder or ZIP, check the detected languages, start one translation run, and download the successful results together.

Bulk translation without the file-by-file busywork

Bulk mode is built for seasons, release folders, multilingual archives, and anyone who has more than one subtitle to translate. You can select individual files, choose an entire folder, or upload one non-nested ZIP. Supported inputs include SRT, VTT, ASS, SSA, SBV, and MicroDVD SUB files.

The workflow stays simple:

Drop your subtitle files, folder, or ZIP.
SubDL samples two substantive subtitle cues from each file and uses AI to detect the source language.
Review the result and correct any uncertain language before translating.
Choose one target language, translation tone, and output format.
Follow overall and per-file progress as each subtitle completes.
Download successful files immediately, then download the finished batch as a ZIP.

The limits are generous enough for real TV packs while still protecting the service for everyone: up to 50 subtitle files per batch, 3,000 cues per file, and 30,000 selected cues in one translation run. Ordinary non-subtitle files inside a folder or ZIP are ignored, while unsafe archives are rejected.

What SubDL Plus includes for $3 a month

SubDL Plus is the best fit for viewers who want better subtitles without paying for developer features. It costs $3 per month and includes 60 AI subtitle translations every month—about two full subtitle files per day.

Plus also includes:

Private folder and ZIP bulk translation
Ad-free, instant subtitle downloads with no daily website limit
AI translation inside Stremio and Bazarr when a language is missing
Bilingual output and translation tone presets
Translation history and convenient re-downloads
SubDL profile perks and a Pro badge

Use the full monthly allowance and the headline cost works out to about five cents per translated subtitle file. The annual plan is $25 per year, compared with $36 when paying month by month, which brings the effective cost even lower.

What SubDL Pro adds for $5 a month

SubDL Pro includes everything in Plus, raises the allowance to 120 AI subtitle translations per month, and adds the complete developer toolkit for $5 per month.

Pro is designed for people running subtitle tools, plugins, bots, media servers, or automated workflows. It adds:

30,000 API requests per day
2,000 subtitle downloads per day through the API
Multiple managed API keys that can be rotated or revoked
Search, autocomplete, and best-release matching endpoints
A public translation-job API for plugins and bots
AI title search for difficult or ambiguous releases
Priority support for production workflows

At the full allowance, 120 translations for $5 is a little over four cents per file. The annual plan costs $49 per year instead of $60 month by month. That is strong value for someone who needs both subtitle translation and API access in one subscription.

Private processing and fair credit use

Bulk uploads are kept private on SubDL's server storage. The original bulk source files and translation checkpoints are removed 30 days after the batch finishes, and deleting a batch lets you remove retained files sooner.

One successful translated file uses one subtitle credit. A file that fails or is canceled does not consume that credit, so a single problem file does not charge you for the rest of the batch. Successful files remain individually downloadable, and even a partially successful batch receives a ZIP containing its completed translations.

Plus or Pro: which one should you choose?

Choose Plus if your main goals are subtitle translation, bulk folder and ZIP processing, ad-free downloads, and integrations for your own movie or TV library. It is the straightforward consumer plan, and $3 per month covers more files than most viewers will translate.

Choose Pro if you want everything in Plus plus twice the monthly translations and the developer API. The extra $2 per month is aimed at automation, plugins, bots, and larger media workflows. Bulk translation is also included with SubDL Max for application-scale customers.
