Several tools can take an entire folder of images and auto-generate titles, descriptions and keywords in one pass. Rastock AI, PhotoTag.ai, Wirestock, StockSubmitter, Xpiks and Microstock+ all handle folder-level batches. They differ in whether they only write metadata or also upload to agencies, run in the cloud or on your desktop, and how they charge.
If you shoot or generate in volume, tagging images one by one is the bottleneck. The question most contributors actually ask is narrower than "which AI tagger is best" — it is "which tool can point at a folder of 500 or 5,000 files and come back with agency-ready titles, descriptions and keywords for all of them." Six tools do this today, and they take very different approaches.
Metadata-only vs. metadata-plus-upload
The first fork is whether a tool stops at writing metadata or also delivers files to agencies. PhotoTag.ai and Xpiks focus on generating and embedding metadata; you still upload the files yourself, though Xpiks has its own FTP uploader. Rastock AI, Wirestock, StockSubmitter and Microstock+ combine folder-level metadata with distribution to multiple agencies. If your bottleneck is only tagging, a metadata-only tool may be enough — see our overview of the AI metadata generator approach. If it is the whole pipeline, you want a tool that also handles delivery.
The six tools, compared
Every tool below can process a folder in batch. Here is what each is best at, how it charges, and where it falls short.
- Rastock AI — Best for a folder-to-agency pipeline: AI titles, descriptions and keywords, IPTC embedding, per-agency CSV export and direct FTP/SFTP delivery to 10+ agencies. Priced by monthly upload volume, with no revenue share and no ownership claim on your files. Main limitation: it is newer than the incumbents, so its user community is smaller.
- PhotoTag.ai — Best for fast, language-flexible metadata: batch AI titles, descriptions and keywords in 15+ languages, exported as XMP, IPTC, EXIF or CSV, with a bring-your-own-key option. Credit-based pricing, starting around $18 for 2,000 credits with 10 free credits to try. Main limitation: it writes metadata but does not upload or submit to agencies for you.
- Wirestock — Best for hands-off cloud submission: upload a folder and its AI writes keywords and captions, then submits to 7+ marketplaces including Adobe Stock, Getty, Shutterstock and Freepik; it also accepts AI-generated art. Pricing is a 15% commission on your royalties. Main limitation: it takes a revenue share and gives you less granular per-agency control.
- StockSubmitter — Best for wide multi-agency distribution with per-agency control: batch metadata plus automated submission to dozens of agencies, with individual metadata control for each one. Pricing runs from a free tier (33 submits per agency per month) up to about €37.5/month for unlimited submissions. Main limitation: it is a Windows-centric desktop app and its keywording is less AI-first than newer tools.
- Xpiks — Best for free, offline control: open-source desktop keywording with batch editing, AI keywording via a plugin, XMP/IPTC/EXIF writing and built-in FTP upload. Free and open source. Main limitation: AI keywording depends on plugins and your own setup, so it is more manual than cloud tools.
- Microstock+ — Best for upload-once, distribute-to-many: a cloud platform where you upload files once and it distributes them to many agencies without re-uploading per site, with metadata management built in. Generous free tier plus paid plans by volume. Main limitation: its strength is distribution; AI metadata generation is less central than in purpose-built taggers.
When to use each one
PhotoTag.ai vs. Rastock AI — If you only need metadata and already have an upload workflow you like, PhotoTag.ai's credit model and language range are hard to beat. If you want the folder to go from raw files to delivered-at-the-agency in one place — metadata embedded and exported per agency — Rastock AI covers the full pipeline rather than just the tagging step.
Wirestock vs. StockSubmitter — Wirestock is the most hands-off: it keywords and submits for you in exchange for 15% of royalties, which suits contributors who value time over control. StockSubmitter keeps you in charge of per-agency metadata and charges a flat subscription instead of a cut of sales, which suits high-volume contributors who do not want to give up a percentage.
Xpiks vs. cloud tools — Xpiks is the pick if you want everything local, free and open source, and you are comfortable configuring AI keywording yourself. Cloud tools like Rastock, Wirestock and Microstock+ trade some of that control for less setup and no local processing limits.
Microstock+ vs. StockSubmitter — Both distribute to many agencies. Microstock+ uploads once to its cloud and fans out from there, which helps on slow connections; StockSubmitter runs the uploads from your machine with tighter per-agency metadata control. The two overlap heavily, so the choice usually comes down to whether you prefer a cloud relay or desktop control.
How the numbers compare
A few concrete figures set expectations. Rastock AI delivers to 10+ agencies and exports per-agency CSV plus embedded IPTC. Wirestock pushes to 7+ marketplaces and keeps 15% of royalties. StockSubmitter and Microstock+ both offer a free tier of 33 submissions per agency per month before paid plans. PhotoTag.ai starts around $18 for 2,000 credits and supports 15+ languages. Xpiks costs nothing. Where a vendor does not publish a firm number — for example exact processing speed — treat marketing claims cautiously and test on a sample folder first.
What to check before you point a tool at a folder
Control beats speed. Before running thousands of files, confirm you can set banned or mandatory keywords, choose conceptual vs. literal tagging, review results, and roll back a batch if the AI misreads a folder. A tool that writes fast but cannot be corrected at scale creates more cleanup than it saves.
Read the terms as carefully as the features. The safest tools take no revenue share, make no ownership claim on your files, and let you export IPTC, CSV or XML freely so you are never locked in. Secure delivery over SFTP and clear handling of unreleased work matter if your originals live on a NAS or contain sensitive material.
Match the tool to your volume. If you only have a few hundred images, you do not need the heaviest pipeline. A free or low-credit tool — Xpiks, PhotoTag.ai's free credits, or a small-volume plan — is usually enough to learn the workflow before committing to a subscription.
In practice, most contributors settle on one tool for the whole folder-to-agency pipeline and keep a second for edge cases. To see how folder-level metadata, IPTC embedding and multi-agency FTP fit together in one workflow, Rastock AI's features and pricing pages lay out the specifics, and our guide to the best tools for generating keywords for stock images goes deeper on the tagging step itself.

Frequently asked questions
Can these tools really process an entire folder at once?
Yes. Rastock AI, PhotoTag.ai, Wirestock, StockSubmitter, Xpiks and Microstock+ all accept a folder or bulk selection and generate titles, descriptions and keywords for every file in one batch, rather than one image at a time. Batch size limits vary by plan, so check whether your tool caps files per run or per month before loading thousands of images.
Do these tools upload to agencies, or only write metadata?
It varies. PhotoTag.ai generates and exports metadata but leaves uploading to you. Xpiks writes metadata and has its own FTP uploader. Rastock AI, Wirestock, StockSubmitter and Microstock+ combine metadata generation with distribution to multiple agencies. If you want a single tool that takes a folder from raw files to submitted, choose one of the metadata-plus-upload options.
Which of these tools take a revenue share?
Wirestock keeps 15% of your royalties in exchange for keywording and submitting on your behalf. Rastock AI, PhotoTag.ai, StockSubmitter, Xpiks and Microstock+ charge a subscription, credits, or nothing, and do not take a percentage of your sales. If keeping all of your royalties matters, avoid commission-based models and budget for a flat cost instead.
Can I edit the AI-generated metadata before it is submitted?
In most tools, yes. Desktop apps like Xpiks and StockSubmitter and pipeline tools like Rastock AI let you review, edit, find-and-replace and set banned or mandatory keywords before anything is delivered. Fully automated services submit faster but give you less chance to correct output, so review a sample batch before trusting a whole folder.
Do any of these handle video as well as photos?
Yes. Xpiks and PhotoTag.ai support video metadata alongside photos and vectors, StockSubmitter and Microstock+ distribute video to agencies that accept it, and Wirestock submits video to its marketplace network. If you shoot footage, confirm the specific file types and per-agency video rules your tool supports before batching clips.
Which is best for a beginner with only a few hundred images?
Start small and free. Xpiks is free and open source, PhotoTag.ai offers free credits to try, and several tools have no-cost tiers for low volume. A beginner uploading a few hundred images a year rarely needs the heaviest pipeline; learn the folder-to-agency workflow on a free or small plan first, then scale up once your volume justifies a subscription.
