These sections explain the job in plain language and set expectations for what the tool should do well.
To compress a PDF, upload one file, choose a compression preset, and export the smaller version. Compress PDF gives you a smaller-file, balanced, or better-quality preset so you can pick the right tradeoff between size and visual fidelity for how the document will be shared.
A lot of PDFs become too large because they are scan-heavy, image-heavy, or overbuilt for how they are actually used. In those cases the job is not editing the document — it is making it small enough for email, uploads, forms, or storage limits, fast, without opening a heavyweight PDF suite. The compression runs locally in your browser, so the source file stays on your device.
A browser-first PDF compressor often rebuilds each page as an image to keep the workflow local and predictable. That usually shrinks file size well for scanned documents, but it can flatten searchable text, form fields, and annotations in the exported PDF, so the result may no longer be selectable or fillable.
Because of that tradeoff, this tool is best when the goal is sharing within size limits, not preserving every embedded feature. It also will not always make a file smaller: if the source PDF is already efficient, some presets may produce a similar or slightly larger file.
Short answers for the questions people usually have before trying a utility like this.
Yes. This tool is free to use with no sign-up, and it runs entirely in your browser.
No. The compression happens locally in your browser, so the source PDF stays on your device during processing.
Not always. It is most effective on scanned and image-heavy PDFs. If the source is already efficient, some presets may produce a similar or slightly larger file.
Not necessarily. This version rebuilds pages as images, so searchable text, form fields, and annotations can be flattened in the exported PDF.
Pick the smaller-file preset when you need to meet a strict size limit, or the better-quality preset when visual fidelity matters more than maximum size reduction.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
