Everything you need to know about Toolzum.
No. All processing happens entirely in your browser using WebAssembly and JavaScript. Your files never leave your device. We have no servers that receive or store your data.
No account is needed for any tool. All free tools work immediately. A Pro account unlocks higher limits, batch processing, and priority support but is entirely optional.
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 tier supports files up to ~50MB. Pro subscribers can process files up to 2GB with batch support of up to 500 files.
Free users get 10 downloads per day with single-file processing. Pro users get unlimited processing with 6x parallel threads.
Yes. All tools work on any modern browser — desktop, tablet, or phone. Some advanced features (like precise cropping) work best on larger screens.
Yes. Pro subscribers can batch-process up to 500 files at once. Select tools like Bulk Image Resizer, Bulk PDF Merger, and Bulk Audio Converter are designed for batch workflows.
Never. We use privacy-first analytics (PostHog, self-hosted) with no cookies, no tracking pixels, and no IP logging. We have no incentive or mechanism to sell user data.
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 [email protected]. 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.
