About SleekPrompt

Converting a PDF to Word usually means handing a stranger's server a document you may not want to hand anyone — a contract, a payslip, a medical letter, a resume with your home address on it. You upload it, you wait, you download the result, and you take it on faith that the file was deleted afterwards.

Then there is the metering. Three free conversions a day. A watermark unless you subscribe. An account required before you can download the thing you just made. A file size cap that exists only to sell you the paid tier.

SleekPrompt exists because for most of these jobs the upload was never necessary. Modern browsers can parse a PDF, decode a HEIC, re-encode a JPEG, generate a document and run a neural network — all locally. If the work happens on your machine, there is nothing to upload, nothing to delete afterwards, and nothing that costs us money per use. The privacy and the lack of limits come from the same decision.

Every tool here is JavaScript running in your tab. There is no upload endpoint anywhere in the codebase — not one that is disabled or rate-limited, but none at all. The site is static files on a CDN.

That has an honest consequence worth stating: a few conversions genuinely need a server, and we do not pretend otherwise. PDF to Word extracts your text into a real .docx, but it does not reproduce the original page layout, and the tool says so on its own page rather than letting you discover it after the download.

Even the AI tools follow the rule. Background removal and OCR download an open-weight model to your device and run it on your own processor. The model comes down; your image never goes up. Details are in the privacy policy.

Because it costs almost nothing to run. There are no conversion servers to pay for, no per-image AI API bill, and no storage. Serving a static page is cheap, and it is cheap whether ten people use the site or ten thousand.

That is why there is no free tier and paid tier here — no daily cap, no watermark, no account. Metering would be a business decision, not a technical necessity, and there is nothing to meter.

In future the site may carry advertising or affiliate links to cover the domain and keep development going. If that happens it will be disclosed on this page and in the privacy policy before it ships, and it will not become a reason to start collecting your data.

The best-known browser background-removal model is licensed for non-commercial use only. It would have worked well and it is what most tutorials reach for. We use MODNet (Apache-2.0) and BiRefNet-lite (MIT) instead, because shipping a non-commercial model on a site that may one day carry ads would be a licence violation.

The image converter does not offer AVIF output. Browsers accept a request to encode AVIF and silently hand back a PNG with the wrong extension, so offering it would mean giving people mislabelled files. The converter probes what your browser genuinely supports and only offers those formats.

The compressor will not return a file larger than the one you gave it. Re-encoding a flat-colour PNG as JPEG routinely makes it bigger; when that happens the original is kept and marked “already optimal” rather than handing you a worse file and calling it compression.

SleekPrompt is an independent project, not a company. It is built and maintained by one developer, and the source is public — you can read exactly what the tools do rather than taking the claims on this page at face value.

Bug reports and suggestions are welcome through the project repository. If a tool gives you a wrong result, that is worth reporting: correctness matters more here than adding another converter to the list.
