Hieronder laten we zien hoe je één of meerdere PDF-bestanden verkleint.

1. Upload je bestanden

   Bestanden worden veilig geüpload via een versleutelde verbinding. Bestanden blijven veilig. Na verwerking worden ze definitief verwijderd.

   Liever niet je bestanden Uploaden en offline werken?
   Try Sejda Desktop. Dezelfde functies als de online service, en de bestanden verlaten nooit je computer.

   Klik op 'Upload' en selecteer bestanden van je lokale computer.

   Bestanden naar de pagina slepen werkt ook.

   Dropbox- of Google Drive-bestanden

   Je kunt ook PDF-bestanden uit Dropbox of Google Drive kiezen.

   Vouw het 'Upload' menu uit en selecteer je bestanden.

2. Comprimeren PDF

   Click the 'Compress' button and then 'Download' your compressed PDF. Or, click on the 'More options' button for advanced settings.

   The compression algorithm does the following:

   1. Optimizes images
   2. Removes unused fonts and images

3. Configure image quality

   Images are optimized and saved with a JPEG image quality of 65%.

   That is perfect for most scenarios. But, if your need it you can configure a better quality for the optimized images (even if the PDF size will be larger).

   Under 'image quality' select 'Good' or 'Best'.

4. Image resolution (PPI)

   Using the standard settings images are optimized to a '72 PPI' resolution.

   Working in a scenario where higher image resolution is needed? Click 'More options', then select '144 ppi', '288 ppi' or '720 ppi' as the maximum image PPI resolution.

5. Grayscale images

   For lower PDF sizes, when having a lot of images, you can convert images to grayscale.

   Here's an example of a grayscale converted image:

   To use this option select 'grayscale' as 'image conversion'.

6. Faster PDF compression

   Processing each image takes time. A document with many images will take longer to compress.

   Compressing smaller images has little effect over the overall document size. The larger images are what we want to optimize. Choose 'Faster' and we'll skip smaller images and only compress larger ones, saving time.
