PDF-ის შეკუმშვა

Your PDF is too large to email. The portal rejects it. Cloud storage is filling up. Sound familiar? Large PDFs are one of the most common document headaches — email servers reject attachments over 10 or 25 MB, web portals impose strict upload limits, and recipients get frustrated waiting for oversized files to download. Dokk.ai's free online PDF compressor solves this in seconds: reduce PDF file size by up to 90% without visible quality loss, or compress to a specific target size like 1 MB, 5 MB, or 10 MB. Our tool analyzes your document structure and applies the optimal combination of reduction strategies. High-resolution images are downsampled to a resolution appropriate for the intended use — screen viewing, ebook distribution, or professional printing. Duplicate embedded resources such as fonts and color profiles are merged. Hidden metadata, editing history, and unused objects are stripped. The result is the smallest possible file that still looks sharp and professional. Choose from four compression presets to match your needs. Screen quality produces the smallest files — ideal for on-screen viewing and email. Ebook quality balances size and clarity for digital distribution. Print quality preserves image detail for documents destined for a laser printer. High quality applies the lightest compression, reducing size while keeping near-original fidelity for archival or professional publishing. If none of the presets are right, configure image quality and resolution manually, or set a target file size in MB and let the engine iterate until it reaches your goal. The compression is lossless for text, vector graphics, and document structure. Only raster images are resampled, and you control exactly how aggressively. Fonts remain embedded and readable. Hyperlinks, bookmarks, form fields, and annotations survive the compression intact. The output PDF is fully compatible with every PDF viewer — Adobe Acrobat, Preview, Chrome, Firefox, and all mobile readers. Dokk.ai works on every device and operating system. Compress PDFs on Windows, Mac, Linux, iPhone, or Android — all you need is a browser. There is nothing to install or configure. Your files are encrypted during transfer and automatically deleted from our servers after processing. We never read or store your documents. Need to compress multiple files at once? Use our Batch Processing tool to apply the same compression settings to dozens or hundreds of PDFs simultaneously. After compressing, use Merge PDF to combine files, or Add Page Numbers for a finishing touch. Dokk.ai gives you a complete document workflow, not just a single-purpose compressor.
