A small studio for a small job: see the tools

Tools

Two tools. No detours.

Choose the file type, pick a level, download the result. The workflow fits on one screen.

PDF compressor

Take weight out of reports, decks, and scanned documents. Page counts stay exactly where they were.

  • Three compression profiles
  • Page count preserved
  • Up to 20 MB per file

Image optimizer

Resize and recompress oversized photos without upscaling small ones or flattening the detail.

  • JPG, PNG, WebP, GIF
  • Batch up to 20 images
  • Limit-based resizing
Open image optimizer →

How it works

Three steps, one screen.

Nothing is hidden behind an account wall or a second workflow. The result is ready as soon as the request finishes.

  1. 01

    Add a file

    Choose a PDF or image, or drag up to 20 files into the queue. Each file can be up to 20 MB.

  2. 02

    Choose a level

    Light keeps more detail. Balanced is the default. Strong takes the most weight off.

  3. 03

    Download the result

    The new size is shown before you download. Sign in if you want the run added to your history.

The details

Built around the file, not the dashboard.

The useful parts are visible: the level you chose, the size before and after, and a record of what happened. Everything else stays out of the way.

How the studio works

Quality-first profiles

Images only scale down, and PDFs keep their page count. Compression should not quietly rewrite the file.

Batch without the mess

Queue up to 20 images. Each row keeps its own original name, result size, and download.

History you can audit

Every signed-in run records both byte counts and a timestamp. Delete any entry permanently.

Private by default

Temporary uploads are removed after each request. Anonymous runs leave no account history.

The result

Every run has a number.

No vague “optimized” label. You see the original size, the compressed size, and the difference before you download.

Questions

Before you start.

The short answers are here. The help page has the longer version, including how files move through the compression providers.

Visit help
Do I need an account to compress a file?
No. The public PDF compressor and image optimizer work without signing in. An account is only needed for history, batch runs in the studio, and analytics.
What happens to my files after compression?
Uploads are processed through Cloudinary for images and pdf.co for PDFs. Temporary copies on our server are deleted as soon as the request finishes. A history entry stores the processed file URL, original name, sizes, and timestamp. Nothing more.
Which formats and limits are supported?
PDF, JPG, PNG, WebP, and GIF. Each file can be up to 20 MB. A single batch can hold up to 20 images; PDFs are processed one at a time so each compression gets a clean run.
What do the three levels actually change?
Light keeps more pixels and higher quality. Balanced is the everyday default. Strong caps dimensions and lowers quality for the smallest output. Images only scale down, and PDFs keep their page count at every level.
Are my files stored forever?
No. Only the compressed result is hosted, by the compression provider. You can remove any history entry from the studio, which deletes our record of it. The provider's copy is subject to their retention policy.
Is it free?
Yes. Compressing files and keeping a history are free. There is no card, trial timer, or paywalled download.
