Nexvert vs iLovePDF: Two Different Ways to Convert a File

The short answer

Both tools merge, split, compress and convert PDFs for free in a browser. The difference is architectural: iLovePDF uploads your file to its servers, does the work there, and sends the result back. Nexvert does the work inside the browser tab you already have open, so the file never leaves your device.

That single difference drives almost every other trade-off. Server processing is more capable; browser processing is more private. Pick based on the document in front of you, not on which site is "better".

How iLovePDF handles your files

iLovePDF is a Spanish company (ILOVEPDF, S.L., based in Barcelona) operating under GDPR. Its privacy policy is specific about what happens to an uploaded file: iLovePDF acts as a data processor while you remain the data controller, and it states that uploaded content is deleted from its servers within two hours of being processed.

The policy also states that iLovePDF does not access, analyse, review or index file contents beyond what is needed to deliver the service, and explicitly commits that customer content is not used to train AI models. The company has an appointed Data Protection Officer and uses standard contractual clauses for transfers outside the European Economic Area, though it notes that for users outside the EEA it may process data in regions closer to the user.

These are serious, legally meaningful commitments, and better than many competitors offer. Anyone comparing the two should start from the fact that iLovePDF is a legitimate operator with a solid privacy posture — not a cautionary tale.

How Nexvert handles your files

Nexvert never uploads the file. Conversions run in the browser using WebAssembly and browser APIs — pdf-lib and pdf.js for documents, ffmpeg.wasm for audio and video, Tesseract for OCR, and Canvas for images. The file is read into the tab's memory, processed, and handed back as a download. Closing the tab discards it.

The practical consequence is that there is no retention window to trust, no cross-border transfer to document, and no processor relationship to rely on — because no copy is ever created off your device. You can verify this yourself: open your browser's developer tools, switch to the Network tab, and run a conversion. No request carries your file.

This is the difference between a promise and a property. iLovePDF promises to delete your file within two hours and is contractually bound to that. Nexvert has nothing to delete. Both can be trusted; they ask you to trust different things.

Where iLovePDF is the better choice

Browser processing has real limits, and pretending otherwise would be dishonest. Choose iLovePDF when:

• •The file is large. A server has far more memory than a browser tab, especially on a phone. Very large PDFs and long videos are more reliable server-side.
• •You need high-fidelity PDF to Word conversion. Reconstructing an editable Word document from a PDF is genuinely hard, and server-side engines do it better than anything that fits in a browser.
• •You want desktop or mobile apps. iLovePDF ships native apps for Windows, macOS, iOS and Android; Nexvert is a website.
• •You need an API. iLovePDF offers iLoveAPI for programmatic conversion. Nexvert has no API at all — every tool is an interactive page.
• •You want an account, saved files, or e-signature workflows through iLoveSign.
• •Your device is old or low-powered. WebAssembly asks your own CPU to do the work, so a slow machine converts slowly.

Where Nexvert is the better choice

Choose Nexvert when:

• •The document is confidential. Contracts, medical records, passports, financial statements, unreleased work — anything where "deleted within two hours" is still two hours longer than you would like.
• •Your employer or client forbids uploading documents to third-party services. A browser-based tool does not trigger that rule, because nothing is transmitted.
• •You are offline, or on a connection too slow to upload a large file. Nexvert works once the page has loaded.
• •You do not want a task limit, a sign-up, or a watermark. Nexvert has none of these.
• •You want to verify the claim rather than accept it. The Network tab settles it in ten seconds.

Side by side

The differences that follow from architecture rather than pricing, which changes:

• •File handling: iLovePDF uploads and processes on its servers, deleting content within two hours. Nexvert processes in the browser; nothing is uploaded.
• •Verifiability: iLovePDF asks you to trust a documented policy. Nexvert can be checked in your browser's Network tab.
• •Large files: iLovePDF is more reliable, since server memory exceeds a browser tab's.
• •PDF to Word fidelity: iLovePDF is stronger; this is hard to do well client-side.
• •Apps and API: iLovePDF has desktop apps, mobile apps and iLoveAPI. Nexvert has none.
• •Accounts: iLovePDF offers them and free-tier limits apply. Nexvert requires no account.
• •Speed: iLovePDF depends on your upload bandwidth; Nexvert depends on your device's CPU.

A note on this comparison
