Everything you need to know about Toolzum.
For the majority of tools: no — all processing happens entirely in your browser using WebAssembly and JavaScript. Your files never reach our servers. A small number of AI-powered tools send data directly from your browser to a third-party AI API; these are clearly marked on every tool page. Either way, your files never touch Toolzum's infrastructure.
No account is needed for any tool. All free tools work immediately. Signing in free raises limits to 5 downloads/day, 30 AI credits/month, and batches up to 10 files (150MB each). A Pro account adds unlimited downloads, 500-file batches up to 2GB, batch ZIP downloads, and 300 AI credits/month.
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.
Free anonymous users can process files up to 10-30MB depending on file type (images 10MB, PDFs 15MB, audio 20MB, video 30MB). Signing in increases limits to 20-150MB. Pro subscribers can process files up to 2GB with batch support of up to 500 files.
Anonymous users get 3 downloads per day. Signing in free raises the limit to 5 downloads per day with batches up to 10 files. Pro users get unlimited downloads with 6x parallel threads and batches up to 500 files.
AI text tools (paraphraser, translator, summariser) cost 1 credit per use; voice/video transcription costs 10 credits per use. Signing in free gives 30 credits/month; Pro gives 300/month, resetting monthly. AI image generation and all local tools are free and use no credits. Anonymous users need to sign in to use AI tools.
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 300 AI credits/month.
Batch ZIP download is a Pro feature. Free users download files individually; Pro users get 1-click ZIP archives for entire batches plus saved workflow presets.
Yes. All tools work on any modern browser — desktop, tablet, or phone. Some advanced features (like precise cropping) work best on larger screens.
Yes. Free signed-in users can batch up to 10 files at a time (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.
Never. We use privacy-preserving analytics (PostHog page views you can Decline, plus cookieless aggregate metrics) 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.
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.
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.
You can cancel anytime from the Billing page or by emailing support@toolzum.com. Your Pro access continues until the end of the billing period.
Toolzum is built by a small independent team focused on privacy-first, client-side web utilities. We believe powerful tools shouldn't require surrendering your data.
