Frequently Asked Questions
What sets BulkWizards apart from other online tool suites?
The image, PDF, document and calculator tools run in your browser, so your files are not uploaded to us and you can work on many files at once. The exceptions are the ones that need to share something: the URL shortener and the shareable wedding invitation store what you create so the link works for others.
Is my data safe with your salary and finance calculators?
Yes. The calculators work in your browser, so the salary, loan and investment figures you type are not sent to our servers.
Are there really no limits on the number of files I can process?
There's no daily cap, no subscription, and no fee. Batch sizes depend on the tool and are shown on its page (for example up to 50 photos at a time in the background remover), to keep things fast in your browser — once a batch finishes, start another right away, as many times as you like.
Do you add watermarks to images or PDF documents?
No. Converted images, merged PDFs, certificates, invoices and other files are saved without a watermark or our logo.
Which categories of tools are available on BulkWizards?
Image tools (convert, compress, resize, crop, remove backgrounds), PDF tools (merge, split, compress, sign, OCR and more), generators (certificates, ID cards, invoices, resumes, QR codes, barcodes, passwords), calculators (salary, profit margin, SIP, EMI, FD and RD, PPF) and utilities such as a file renamer and URL shortener.
Why don't I need to create an account or sign in?
Because the tools run in your browser, there is nothing to store for you, so you can use them without an account. Signing in is optional; it lets you keep your short links and saved items in one place.
