Comprimir PDF a 100KB o Menos

Llegar a 100KB depende mucho de qué haya adentro del PDF. Los documentos de solo texto normalmente ya están bien por debajo de 100KB y no necesitan ayuda. Los PDF con una o dos fotos JPEG suelen alcanzar ese objetivo con el nivel Alto de compresión de abajo, que reduce la resolución de las imágenes de forma agresiva y baja la calidad JPEG. Pero un PDF con muchas fotos, o con páginas escaneadas en vez de texto real, puede no llegar a 100KB sin pérdida de calidad visible — en ese punto la respuesta honesta es que cierta degradación visual es el costo de ese tamaño de archivo, no una limitación puntual de esta herramienta.

Your PDF is processed directly in your browser's memory using a client-side library — nothing is uploaded to any server.

How to use this PDF compressor

  1. Select a PDF file.
  2. Pick a compression level and click "Compress & Download".
  3. The reduced file downloads automatically, and you'll see exactly how much size was saved.

How does this actually reduce file size?

Document metadata (author, title, producer info) is stripped, and the file structure is re-optimized. Any embedded JPEG images are downsampled and recompressed at the level you choose — this is where most of the size reduction comes from on image-heavy PDFs, since photos are usually the largest part of a file by far.

How much smaller will my file get?

It depends entirely on the content. PDFs with embedded JPEG photos can shrink dramatically — commonly 50-80% — since those images get downsampled and recompressed. A text-only PDF with no images will only shrink a small amount (typically under 10%), from removing metadata and optimizing the file structure, since text content is already compact.

Does this work on all embedded images?

Only JPEG images are recompressed. PNG images and other raster formats embedded in the PDF are left untouched and don't contribute to the size reduction — this is a limitation of what can be reliably decoded and re-encoded client-side.
