Most file problems are small and urgent: a portal that only takes JPG, a spreadsheet someone needs as CSV, a video clip you want as an MP3, a PDF that is too big to email. Installing software for a one-off job is overkill, and uploading private files to an unknown server is a risk many people would rather not take.
The quick converter above handles the common cases in one place. Drop a file and it recognises the type from the extension and MIME type, shows only the conversions that make sense for it, and opens the right converter with your file already loaded.
Everything on this page runs inside your browser. Images are re-encoded with the browser's own codecs, audio and video are decoded with the Web Audio and media APIs, and spreadsheets and documents are parsed with open-source JavaScript libraries. Your files are not sent to our server.
How It Works
- Drop a file — the converter reads the file name and MIME type to decide what it is: image, audio, video, spreadsheet, CSV, JSON, Word document, text or PDF. Nothing is uploaded at this stage or later.
- Pick a target — only sensible options appear. A PNG offers JPG, WebP, GIF, BMP and more; a video offers MP3, GIF or JPG frames; an XLSX offers CSV. Jobs that need a specialised tool, such as compressing a PDF or Word to PDF, link straight to that tool's page.
- Convert and download — the matching engine loads on demand, converts the file on your device, reports the new size and gives you a download link, or a ZIP when you converted several files at once.

Unsupported Formats
Video-to-video conversion (for example MKV to MP4) is not offered, because re-encoding video in a browser is slow and unreliable on most devices. Old binary Office formats (.doc, .ppt) must be saved as .docx or .pptx first. DRM-protected media, RAW camera files and CAD drawings are not supported. Files that fail to decode get a clear error instead of an empty download.
File Size Limits
Limits are set per tool according to what a browser handles comfortably: up to 60 MB per image or spreadsheet, 300 MB per audio file and 500 MB per video. Because the work happens on your device, a modern laptop converts large files much faster than an older phone.
Who Should Use This Tool?
- Students: A student photographs a worksheet on an iPhone and turns the HEIC file into a JPG that the school portal accepts.
- Freelancers & Designers: A designer converts twenty PNG mockups to WebP in one batch and downloads them as a ZIP for a client site.
- Office Professionals: An accounts assistant turns a monthly XLSX export into CSV for the bookkeeping system without opening Excel.
- Developers: A developer converts an API's JSON response into CSV to share with a colleague who works in spreadsheets.
Key Features / Khusoosiyat
Here's what separates this tool from generic alternatives:
Automatic Detection
The file type is recognised for you, so you only see conversions that work.
Runs on Your Device
Conversions happen in the browser; files are not uploaded.
Batch + ZIP
Convert several images, audio files or spreadsheets together.
No Watermark
Output files are clean, with nothing added.
Honest Errors
Unsupported or damaged files get a clear message, not a broken download.
140+ Tools
Specialised PDF, image, audio, text and developer tools one click away.
Why This Tool Beats the Alternatives
- No account, email address or daily conversion quota.
- Files stay on your device instead of waiting in a server queue.
- No watermark on images, PDFs or audio.
- Starts converting as soon as the engine loads — no upload wait for large files.
- Image, audio, video, data and PDF tools in one place with consistent controls.
Pro Tips
- For photos, JPG or WebP at 80–90% quality looks identical to the original and is far smaller than PNG.
- Converting a folder of images? Select them all at once — they are processed in one batch and returned as a ZIP.
- If a PDF is too large for email, try Compress PDF before converting it to anything else.
