Upload a PDF and choose Light, Balanced, or Strong compression. By default, the tool runs in your browser: it strips metadata, rebuilds page structure, and can flatten form fields. Embedded images are not recompressed, so savings vary. Files are not uploaded to a server.
Runs in your browser by default: it optimizes PDF structure and metadata. It does not recompress embedded images, so image-heavy or already-optimized PDFs may not shrink much.

Upload a PDF and choose Light, Balanced, or Strong compression. By default, the tool runs in your browser: it strips metadata, rebuilds page structure, and can flatten form fields. Embedded images are not recompressed, so savings vary. Files are not uploaded to a server.
Use the Compress PDF form near the top of this page. Enter the values you know, run the tool, and review the results panel. You can change inputs and run it again. Processing stays in your browser and is not uploaded to Utilnivo servers.
Example: open Compress PDF, enter a realistic set of inputs for your situation, and note the primary result. Change one input—such as an amount, rate, or option—and compare how the output changes so you can choose a scenario that fits your needs.
Second example: try edge cases that matter for your task—such as zero values, a different unit system, or a second file—and confirm the tool shows a clear result or a helpful validation message.
Upload a PDF and choose a compression level. By default, compression runs in your browser: it strips metadata, rebuilds page structure, and can flatten form fields. Embedded images are not recompressed, so savings vary. An optional Ghostscript/qpdf API can be configured for stronger server-side compression.

No, by default. Compression runs in your browser and files are not uploaded. An optional Ghostscript/qpdf API can be configured for stronger server-side compression.
Light strips metadata and enables object streams. Balanced also rebuilds page structure. Strong does the same and flattens form fields when present. Embedded images are not recompressed in browser mode.
No. Already-optimized or image-heavy PDFs may not shrink. If no savings are found, the original file is offered for download.
