Compress a PDF Portfolio

Typically 50–70% using Less Compression, with no artefacts visible at normal viewing distance. Portfolios are usually oversized because images sit at 600 DPI print resolution when they will only ever be viewed on a screen — reclaiming that costs nothing perceptible.

Aim for 10–20 MB for email and most submission portals. Architecture and photography portfolios often start above 200 MB. If a portal caps you at 10 MB, use Target Size mode and inspect the output carefully before submitting.

Embedded ICC colour profiles are preserved, so colour management is maintained. Aggressive JPEG re-encoding can theoretically shift subtle gradients, which is precisely why this page defaults to the highest-quality preset. For a print portfolio, always verify the output before sending it to a printer.

Your PDF was probably already optimized — for instance exported by Acrobat with compression enabled, or generated as pure text with subset fonts. When we cannot beat the original we deliberately return your untouched file rather than a worse one.

Yes. Bookmarks, the table of contents, internal cross-references, hyperlink annotations and interactive form fields all survive compression. Only the encoding of images and content streams is altered — the document's structural and navigational layers are preserved.

Not while it is encrypted. A protected PDF has its content streams encrypted, so the compressor cannot read the images it needs to optimize. Remove the password in your PDF reader first, compress, then re-apply protection to the smaller output if you still need it.

Very well, because the file itself is never transmitted. Only the page and the compression engine are downloaded, once, and they are then cached. Uploading a 100 MB PDF to a server-based tool would consume 100 MB of your data allowance; here it consumes none.

It depends on the content. Scanned or image-heavy documents commonly shrink by 70–95%. Text-only PDFs that were already optimized may only drop 5–20%, since there is little redundant data left to remove.

Yes. The interface is fully responsive and the engine runs on iOS and Android. Bear in mind that mobile devices have less memory, so very large files (over roughly 50 MB) may be slow or fail on older phones.

Page dimensions, margins and layout are always preserved exactly. Print appearance only changes if images are downsampled below your printer's resolution. Less Compression holds images near 200 DPI, which prints cleanly on any office printer; avoid Extreme mode for anything going to paper.
