Frequently Asked Questions
Everything you need to know about Toolzum.
Are my files uploaded to any server?
For the majority of tools: no — all processing happens entirely in your browser using WebAssembly and JavaScript. A small number of clearly-marked AI and cloud tools send your input to our server, which forwards it to our AI provider (Google Gemini) — we store none of your content. See our Privacy Policy for the full data-flow list.
Do I need to create an account?
No account is needed for local tools — they run immediately with unlimited downloads. AI credit tools (image generation, transcription, AI describe) require a free sign-in; you get 5 one-time trial credits. Signing in free also raises batch limits to 25 files. Pro adds 500-file batches up to 2GB, batch ZIP downloads, and 200 AI credits/month.
What file formats are supported?
We support hundreds of formats: images (JPG, PNG, WebP, HEIC, SVG, AVIF), documents (PDF, DOCX, PPTX, XLSX), audio (MP3, WAV, FLAC, OGG, M4A), video (MP4, AVI, MOV, MKV, WebM, GIF), and more.
Is there a file size limit?
Generous per-type ceilings, same for guests and signed-in users: images 50MB, PDFs 125MB, audio 100MB, video 250MB. Pro subscribers can process files up to 2GB with batch support of up to 500 files.
How many files can I process?
Downloads on local tools are unlimited for everyone, no account needed. Signing in free adds 5 trial AI credits and batches up to 25 files. Pro users get 500-file batches, 6 parallel threads, 2 GB files, batch ZIP, and 200 AI credits/month. Local downloads are already unlimited on every plan.
How do AI credits work?
AI text tools (paraphraser, translator, summariser) cost 1 credit per use; voice/video transcription costs 1 credit per minute of audio; Gemini HD image generation costs 5 per use (the standard Pollinations engine stays free). Signing in free gives 5 trial credits, one-time and never refilled; Pro gives 200/month, resetting monthly. All local tools use no credits. Anonymous users can use the free Pollinations image engine; all credit-backed AI tools (and Pro tools) require a free sign-in.
Can I try Pro tools for free?
Yes. Guests see a sign-in screen on Pro tools, but signing in free unlocks 2 Pro-tool downloads per day — enough to evaluate any premium tool. Upgrade to Pro for unlimited downloads, 500-file batches, batch ZIP, and 200 AI credits/month.
Can I download multiple files as a single ZIP?
Batch ZIP download is a Pro feature in the bulk-processing shells; a few single-purpose generators (e.g. Bulk QR Code Generator) produce ZIPs within the free limit. Free users in batch shells download files individually; Pro users get 1-click ZIP archives for entire batches plus saved workflow presets.
Is Toolzum accessible on mobile?
Yes. All tools work on any modern browser — desktop, tablet, or phone. Some advanced features (like precise cropping) work best on larger screens.
Do you support bulk/batch processing?
Yes. Guests batch up to 5 files at a time and free signed-in users up to 25 files (processed one by one, downloaded individually). Pro subscribers batch up to 500 files in parallel with 1-click ZIP download. Select tools like Bulk Image Resizer, Bulk PDF Merger, and Bulk Audio Converter are designed for batch workflows.
Is my data tracked or sold?
Never. We use privacy-preserving analytics (PostHog and Microsoft Clarity, both switched off once you Decline; Cloudflare Web Analytics is cookieless and always on) with strictly-necessary storage for sessions and free-tier quota. No advertising trackers, no cross-site profiling, no data sale — IP addresses are used only for rate-limiting, never stored with analytics. Full details in our Privacy Policy.
What happens if I close the browser during processing?
Processing stops and any results are lost. Since everything runs client-side, there is no server-side job queue. Re-open the tool and start again.
Can I use Toolzum offline?
Most tools require an initial page load but then work without internet for the actual processing. The service worker caches the app shell for repeat visits.
How do I cancel my Pro subscription?
You can cancel anytime by emailing contact@toolzum.com. Your Pro access continues until the end of the billing period.
Can I get a refund?
Yes. Your first Pro purchase is fully refundable within 14 days if you have used fewer than 20 AI credits, and EU/EEA and UK consumers keep their statutory 14-day withdrawal right regardless of usage. The 7-Day Project Pass is non-refundable outside the EU/EEA and UK; inside those, the statutory 14-day right applies. An unwanted renewal can be refunded within 7 days if its credits are unused. Email contact@toolzum.com with the subject 'Refund request' — full details on the Refund Policy page.
Who built Toolzum?
Toolzum is built and run by solo founder Kirtiwardhan Rathore — bootstrapped, no outside funding — focused on privacy-first tools that run in your browser so your files never leave your device. Full story on the About page.
