A format for the next step.

Supported workflows in the free browser edition.

Images

Input: PNG, JPG/JPEG, WebP, GIF, BMP. Output: PNG, JPG, WebP, or a combined PDF. Animated GIF and WebP inputs become still images. JPG output uses a white background for transparency. Resizing preserves proportions and never enlarges smaller images.

PDF

Combine documents, extract pages, rotate all pages, or render selected pages as PNG/JPG. Multiple rendered pages download in a ZIP. Encrypted PDFs are not supported. PDF edits can invalidate digital signatures; keep the original document.

Structured data

CSV to JSON and flat JSON arrays to CSV. JSON formatting accepts any valid JSON value. CSV values stay as strings to preserve identifiers and leading zeros. Nested JSON objects cannot be converted to CSV directly.

Audio

MP3, M4A, AAC, OGG, FLAC, WAV, or WebM input when your browser can decode the codec. Output: 16-bit PCM WAV. Output size may increase. MP3 encoding and video conversion are not included.
