FileOnTap vs Grabivo JFIF to PNG Converter: Which Is Better in 2026?

FileOnTap is a free browser-local File Converter for HEIC, WebP, PNG, and JPG files. Convert images between supported formats, compress images, and convert images to PDF or PDF pages to images directly in your browser. Files stay on your device: there is no upload, no account, and no watermark. Use it for quick, private file conversions without installing software. FileOnTap is designed for anyone who needs a simple image converter and image-to-PDF tool on the web.

What problem it solves

Many online converters require uploads, accounts, or add watermarks. FileOnTap makes private, quick image and PDF conversion possible directly in the browser.

Grabivo JFIF to PNG Converter turns JFIF images into PNG files directly in your browser. JFIF is a container format that many cameras, scanners, older software and some messaging apps still produce. It is essentially a JPEG, but plenty of editors, upload forms and content management systems do not recognise the .jfif extension. Converting to PNG gives you a file that opens almost everywhere, keeps sharp edges and text clean, and supports transparency if you later edit it.

How it works is simple. Open the converter page, drop one or several JFIF files onto it, and the PNG versions are produced right away. The conversion runs locally on your device, so nothing is uploaded to a server and nothing is stored. There is no account to create, no email to confirm and no software to install. You pick the files, you get the results, and you close the tab when you are done.

Who is it for? Anyone who has received a picture with an unfamiliar .jfif extension and just wants a normal image: students submitting assignments, designers collecting reference material, people filling in online applications that only accept PNG or JPG, and teams moving images between tools that handle formats differently. Because everything happens in the browser, it also suits people who handle personal or work photos and prefer that the files never leave their computer.

Grabivo is more than a single converter. The same site offers browser-based video, image and PDF tools, plus everyday unit converters, calculators and text tools. Examples include merging and splitting PDFs, compressing and trimming video, resizing and cropping images, converting between HEIC, WebP, JPG and PNG, and quick utilities such as a word counter, a hash generator or a percentage calculator. Every tool follows the same idea: open the page, use the tool, leave without signing up for anything.

The interface is available in 20 languages, so the converter is usable by people in many countries without extra setup. Pages are light and load quickly, and the tools work on desktop and mobile browsers alike. If you regularly need to change image formats, you can keep the page bookmarked and use it whenever a stubborn file shows up. The service is offered at no cost, with no usage tiers to choose from, and there are no accounts, so there is nothing to manage or cancel.
