Fileswin is a collection of simple tools for everyday jobs. Image conversion, PDF compression and file checks run in your browser, rather than through a Fileswin file-upload service. Your device handles the work, so performance can depend on its memory and browser. Market prices refresh when the data provider responds; they are useful references, not guaranteed trading quotes.
Fileswin brings together practical browser-based tools and market reference pages. Check cryptocurrency market values, estimate gold and silver content by weight and purity, convert supported iPhone photos to JPG, reduce some PDF file sizes, and calculate file checksums. Each tool page explains what its result means and where its limitations matter.
Gold and silver are commonly quoted in US dollars per troy ounce, while jewellery is often weighed in grams. Our gold price calculator estimates metal value by karat, and the silver price calculator estimates value by weight and fineness. Spot prices are indicative market references: retail premiums, workmanship, taxes, testing and dealer spreads can change the price paid or received.
Use the crypto converter to estimate the value of supported digital assets in common currencies. Cryptocurrency rates can change quickly and vary across exchanges. The converter is informational and does not execute trades or include exchange fees.
The HEIC to JPG converter helps with image compatibility, the PDF compressor can rewrite and optimize some documents, and the file hash checker calculates checksums such as SHA-256. Check each tool's instructions and verify downloaded results before using them. You can also create a QR code, reduce image size with the image compressor, change dimensions using the image resizer, count text with the word counter, or create a random password with the password generator. You can also merge PDFs, format JSON, calculate your age or a percentage, convert currencies, create an invoice, or change an image format.
The tools on this site are provided free to use. Some market-data services and browser capabilities depend on third-party providers and may occasionally be unavailable.
No. They are indicative data for reference and may differ from prices, spreads and fees offered by a broker, dealer or exchange.
The file tools are designed to process files locally in your browser. You should still review the tool description and your browser's network activity if handling sensitive documents.
