Frequently Asked Questions

Quick answers on PDF tools, image compression, calculators and privacy. Every tool is free and runs in your browser.

Are Lupusmart’s online PDF tools really free, with no signup?

Yes. Every Lupusmart tool is free to use with no account, no signup and no usage limit. Open a tool, add your file and download the result. That includes merging, splitting, compressing, signing and converting PDFs.

How do I compress a PDF online without uploading it to a server?

Open the Compress PDF tool, select your file and download the smaller version. Lupusmart compresses PDFs inside your browser, so the file stays on your device and is never sent to a server.

How do I reduce an image to 20 KB, 50 KB or 100 KB?

Use the Image Size (KB) tool. Upload a JPG, PNG or WebP image, enter the target size in KB and download the compressed file. It is built for government forms, exam portals and job applications that set a strict size limit.

How do I merge PDF files for free?

Open Merge PDF, add two or more PDF files, arrange them in the order you want and download one combined PDF. No signup is needed and the files are processed in your browser.

Is it safe to use online PDF tools? Are my files uploaded?

Lupusmart processes files on your own device using your browser. Your documents, images, audio and video are not uploaded or stored on our servers, which makes the tools suitable for private documents such as contracts and ID proofs.

How can I sign a PDF online from my phone?

Open Sign PDF, add your document and draw your signature with your finger or a stylus on the touchscreen. Place it on the page and download the signed PDF. It works on mobile and desktop browsers.

How do I convert PDF to JPG or PNG in high quality?

Use PDF to Image. Choose PNG for lossless quality or JPG for smaller files, select a resolution up to 600 DPI (4K), and download every page as a separate image.

How do I calculate my loan EMI online?

Open the EMI Calculator and enter the loan amount, yearly interest rate and tenure. It shows your monthly EMI, total interest, total payment and a year-wise schedule. For example, a ₹10,00,000 loan at 8.5% for 20 years has an EMI of about ₹8,678.

How do I make a passport size photo online for free?

Use the Passport Photo tool in the Image Suite. Upload a clear photo, choose the ID size you need, then download the cropped result. Everything runs in your browser, so your photo stays private.

How can I convert handwriting to text online?

Use the Handwriting to Text tool. Upload a photo or scan, choose the language and copy the extracted text. It works best on neat writing or print, and messy cursive may need manual corrections.

How do I generate a strong, secure password?

Use the Password & Passphrase Generator. Set the length (14 to 24 characters is recommended) and copy the result. Passwords are created with your browser’s cryptographic random number generator and are never sent over the network.

Can I create a QR code for a link, phone number or UPI ID for free?

Yes. Enter any URL, text, phone number or UPI string in the QR Code Generator, choose the size and colour, then download it as PNG or PDF. There is no watermark and no signup.

How do I add a free chatbot to my website?

Use the Chatbot Maker in Developer Tools. Add your questions and answers, test the bot live, then copy the embed code and paste it into your website’s HTML block.

Google Chrome and Microsoft Edge give the best results for the Audio Cutter, Video to MP3, GIF and video compression tools.
