PDF pages

Leave empty for all, or type e.g. 1-3, 5, 8-

Resolution
Compression

Text, vector graphics, links and forms stay exactly as they are; only images are re-encoded. If a file cannot get smaller, you get the original back.

Output
Worksheets
Separator

Columns are found from how the text lines up. Clear tables work best; check merged cells and headers after converting.

Fonts are replaced by Word’s standard font; complex layouts (columns, text boxes) become simple paragraphs you can edit.

Slide quality

Each page becomes one slide that looks exactly like the PDF. The text in the notes can be copied into your own slides.

Text layout

The first time, the engine and language data (about 2–8 MB) are downloaded from this site; after that it runs on your device.

PDF document
Paper size
Orientation

Values are printed as Excel shows them (dates, decimals, percentages). Charts, pictures and cell colours are not included.

PDF document
Slides per page

2, 4 or 6 slides per A4 page make printable handouts.

Text, shapes, pictures and tables are drawn in their places; fonts are replaced by a standard font, so line breaks can differ a little. Charts, SmartArt and videos are not included.

Video

Lower resolutions reduce file size. The video will not be enlarged.

Lower values mean higher quality and larger files. Applies to H.264, VP9, MPEG-4 and MPEG-2 outputs.

Choose a video encoder supported by the output format.

Subtitle tracks are embedded in the video. Burning makes text permanent in the picture.

PNG, JPEG or WebP up to 5 MB. The logo is placed at 25% of the video width.

Choose an audio codec supported by the output format.

Audio
Bitrate

Higher means better sound and a larger file. “Auto” keeps the bitrate of the original (at least 128 kbit/s); from lossless files it uses the format’s high-quality setting.

Sample rate
Channels
Cut (optional)

Times such as 1:30 or 0:45.5. Leave empty to keep the whole recording.

Picture

The video shows this picture for the whole length of the sound – for example to upload music or a podcast to YouTube.

Document
Resolution
Pages to convert

Several pages arrive as a ZIP with one image per page.

Shown by e-readers in the library; leave empty to keep what the document says.

PDF/A-2b embeds all fonts so the file looks the same in many years; required by many courts and public offices.

Scales every sheet so it fits on a single page instead of being split across several.

Sheets

CSV and TSV hold one table: with “Every sheet” each sheet becomes its own file, together in a ZIP.

Separator

Excel in many European languages expects a semicolon; most other programs a comma.

Convert on our server?

If you continue, the file is uploaded over an encrypted connection and converted on our server. You can keep using the site meanwhile. The original is deleted as soon as it is converted; the result is kept for 6 hours so you can download it, and you can delete it at any time. Files are never shared or used for anything else.
