File converters: bridge every format that refuses to cooperate

Every workflow eventually hits a format wall: the phone saves HEIC but the site wants JPG, the accountant sends Excel but the system imports CSV, the video editor exports SRT subtitles but the player needs VTT, the screenshot contains text you need in a document. The nine converters here are format bridges — most run locally in your browser, the heavier OCR jobs run server-side.

Images: Image Convert moves files between JPG, PNG, WebP, and more with quality control — the everyday answer to "this site only accepts PNG". Image to Text and Image OCR read text out of screenshots, photos of whiteboards, and scanned pages, turning pictures into editable, searchable words.

Documents and data: Excel to CSV and CSV to Excel handle the classic spreadsheet handoff — clean delimiter and encoding control included, which matters more than people think until an import chokes on a stray semicolon. Word to HTML strips pasted documents into clean markup for CMS editors. Text to PDF produces clean printable documents from plain text.

Video text: Subtitle Converter moves between SRT, VTT, and ASS formats with timing preserved — the tool you need the day a player rejects your subtitle file. Subtitle Translate goes further, translating subtitle files to other languages while keeping the timing intact.

How to choose: match the tool to the direction you are moving — image, data, document, or subtitle — and prefer local tools when the file is personal. Practical tips: after converting spreadsheets, open the result and check the header row and number formats before importing anywhere; OCR reads clean printed text far better than handwriting; and when converting subtitles, spot-check the first and last cue timings against the video.

Frequently asked questions

Does converting Excel to CSV keep my formulas?

CSV is plain text, so formulas are exported as their last computed values. If you need the formulas preserved, keep the original workbook alongside the CSV.

Why does my CSV import show garbled characters?

Almost always an encoding mismatch. The converter lets you choose the encoding — match it to what the importing system expects (UTF-8 for most modern tools, legacy encodings for older software).

Is OCR accurate for screenshots?

Yes, for clean digital screenshots OCR is near-perfect because the text is crisp. Photos of pages and low-resolution images produce more errors; crop and enlarge before recognizing.
