Smaller files, without the guesswork

Four compression tools and an OCR tool. Each one shows what it will really do to your file — every control on these pages reaches the encoder that acts on it.

Compress PDF

Reduce PDF size with quality presets, image downsampling and cleanup of the parts of a document nobody reads — metadata, annotations, stray forms.

Quality preset — Screen, Ebook, Printer, Prepress
Image downsampling at 72 / 150 / 300 DPI
Grayscale and flatten-to-image
Strip metadata, annotations and form fields
Page range selection
Remove document password

Compress Image

The visual one. See every image before and after, pick a quality and format, cap the dimensions, and strip the location data you did not mean to publish.

Quality slider with live before/after thumbnails
Convert to JPEG, WebP, AVIF or PNG
Max width/height with fit, crop or stretch
Target file size — get under a number you choose
Lossless mode for PNG and WebP
Strip EXIF and GPS data

Compress Audio

Choose a bitrate and see what it will cost you in megabytes before you commit. Drop to mono for spoken word, or normalise a batch to a consistent level.

Bitrate ladder with estimated output size per step
Sample rate from 8 kHz to 192 kHz
Mono or stereo, with a note for spoken audio
Loudness normalisation
Warning when a lossless source makes bitrate meaningless
Output to MP3, AAC, OGG, M4A, Opus, WMA, WAV or FLAC

PDF OCR needs a text-recognition engine that is not on the server yet, so it is listed above but not linked. Everything else here runs today.
