About ConvertPro

ConvertPro is a free collection of 20 tools for working with images and PDF files — converting, compressing, resizing, cropping, editing, removing backgrounds, and merging, splitting or rearranging PDF documents. Alongside them are 14 written guides and 12 format conversion pages. Everything runs inside your browser: there is no server here that receives files, no account system, and no database.

Why it exists

The tools grew out of a specific, tedious problem. Indian recruitment and entrance portals — SSC, IBPS, UPSC, RRB, NTA, various state commissions — each demand a photograph and signature at particular pixel dimensions within a particular kilobyte range, in JPEG, and they reject anything that misses. Meeting those constraints means cropping to a ratio, resizing to exact pixels, converting format, and tuning compression, in that order.

The existing options were all unsatisfying. Desktop software is overkill for a 20 KB file. Most free online tools upload your photograph and your signature specimen to a server whose operator you cannot identify and whose retention policy you cannot verify. For a document that authenticates you, that is a genuinely poor trade. So ConvertPro does the work locally instead — a constraint that turned out to be a feature rather than a limitation.

How it is built

The site is a static React application with no backend and no API. Processing uses capabilities the browser already has: the Canvas API for decoding, resizing and re-encoding images; WebAssembly for HEIC decoding and the background-removal neural network; pdf.js and pdf-lib for reading, rendering and writing PDF documents; and JSZip for assembling batch downloads in memory.

You can verify the privacy claim directly: open your browser's developer tools, watch the Network tab while you convert a file, and observe that nothing carrying your data is sent. Or load the page and switch to airplane mode — the tools keep working. We wrote about this in why in-browser file tools are safer than upload-based converters.

How it is funded

ConvertPro is free and carries advertising. We do not sell data, and we could not sell your files even if we wanted to — they never reach us. Advertising relates to your browsing, not to anything you process here; the privacy policy sets out exactly what third parties are involved. There is no paid tier, no upsell, and no feature held back behind a signup.

What we deliberately do not do

Independence

ConvertPro is an independent project. It is not affiliated with, endorsed by or connected to eMitra, SSO Rajasthan, the Government of Rajasthan, any examining body, or any government agency. We do not process applications, submit forms, or collect fees on anyone's behalf. Where our guides describe form requirements, they describe publicly published specifications for your convenience — always confirm against the official notification you are applying under.

Editorial approach

The guides are written in-house, from the questions people actually arrive with. Where a guide states a specification, it says plainly that requirements change and that the official notification takes precedence. Where a tool has a genuine limitation — PDF compression making text non-selectable, AVIF export falling back to WEBP, the GIF encoder being unsuitable for photographs — we say so on the page rather than letting people discover it afterwards. Guides carry a last-updated date and are revised when requirements or browser behaviour change.

Contact

Feedback, corrections and tool requests are welcome — particularly corrections. If a specification in a guide is out of date, telling us helps everyone who reads it next. Reach us at rajeevsaini.dev@gmail.com or through the contact page.
