Reduce PDF files to a practical upload size while keeping them usable for documents, reports, scanned files, and presentations.
Drag in one file or a full batch. The uploader handles typical PDF workflows such as email attachments, website assets, and portal submissions.
フォームの制限を満たす必要がある場合、ページの重量を減らす必要がある場合、または添付ファイルの上限を超えないようにする必要がある場合は、2MB を選択してください。エンジンは圧縮率とビジュアル品質のバランスを自動的に調整します。
圧縮出力を個別にダウンロードするか、ZIP アーカイブとしてダウンロードし、アップロード、公開、共有、またはストレージのクリーンアップにすぐに使用します。
2MB preserves high quality for PDF files. Suitable for printing, detailed viewing, and professional use with minimal visible difference from the original.
At this size, compression is light. Original quality is largely preserved. Fine for any use case including large-format printing and professional production.
PDF is commonly used for documents, reports, scanned files, and presentations. Typical originals land around 1–20 MB, so compressing to 2MB is most useful when you need to meet a strict upload or performance target.
These are the most practical reasons people compress PDF files to 2MB.
Share detailed reports and multi-page documents at 2MB without hitting email or messaging platform limits. Fits within most service caps.
2MB preserves enough detail for standard printing at 150 DPI or higher. Suitable for brochures, flyers, and internal documents.
Reduce your file archive to 2MB per item while maintaining quality. Across thousands of files, the storage and bandwidth savings add up fast.
Built for target-size compression, repeatable results, and practical delivery workflows.
Upload and compress multiple PDF files to exactly 2MB simultaneously. Download all results individually or as a single ZIP archive.
Your files are processed securely and deleted automatically after compression. Nothing is stored, indexed, or shared with anyone. Ever.
Our algorithm iteratively adjusts compression to land as close to 2MB as technically possible — not an approximation, but a precise target.
Compress files directly in the browser. No plugins, desktop apps, or extra setup are required.
Files are processed securely and deleted automatically after compression, which keeps upload workflows private and easier to trust.
GST registration (REG-01) authorised-signatory document bundles and RTI online application attachments accept PDFs up to 2 MB. This is where scanned lease deeds, partnership agreements, and multi-page identity-proof compilations land after compression — the practical ceiling for a 20-30 page scanned document set.
PDF はコンテナです。ファイル サイズは、埋め込み画像 (通常は全体の 70 ～ 95%)、埋め込みフォント (5 ～ 10%)、およびベクター ページ コンテンツ (残り) の 3 つのソースによって決まります。より小さなターゲットへの圧縮は、最初に画像を攻撃します。各埋め込み画像を JPEG で低品質で再圧縮し、次に 300 DPI (印刷品質) から 150 DPI (画面品質) または 96 DPI (モバイル品質) にダウンサンプリングします。 20 MB でスキャンされた 100 ページの PDF は、ページ数やレイアウトに影響を与えることなく、このルートを経由すると 2 MB に達する可能性があります。テキストのみの PDF はすでに限界近くに達しており、15 ～ 20% を超えて圧縮されることはほとんどありません。
PDFs are bigger than they need to be for one main reason — embedded images. Getting a PDF under 2MB is almost always about compressing those images intelligently, not touching the text.
The tool accepts single-file PDFs up to 10 MB on the free plan and up to 1 GB on Pro. Long documents (100+ pages) and scan-heavy PDFs are the ones that benefit most — they usually shrink 60-80% because their weight lives in redundantly-encoded images.
Images inside the PDF are re-encoded at successively lower resolution and quality until the final file lands close to 2MB. Text stays untouched — it remains selectable and searchable. Only the image content is negotiated. If your PDF is mostly text with a few small images, the target may not be reachable without visibly degrading those images; if it\'s scan-heavy, 2MB is usually easily met.
The compressed PDF is ready in a few seconds. Open the result and skim through — text should look identical, image pages should look reasonable at normal zoom. Both the source and the output are permanently deleted from our servers within 30 minutes.
A PDF full of text and small icons might be 200 KB for 50 pages. A single scanned page saved at 300 DPI can be 5 MB by itself. Fonts add a bit; forms and metadata add a bit. But if your PDF is over a few megabytes, it\'s almost certainly image data — either scans, embedded photos, screenshots, or high-resolution charts. That\'s what the compressor negotiates on.
Six situations where hitting the exact byte target is the whole job.
University admissions systems, journal submission portals, and grant applications all publish specific PDF size caps — 2MB is a common ceiling. Missing it means the system rejects the upload silently or forces a resubmission days later.
Immigration portals, tax authorities, and legal filing systems tend to allow modest PDF uploads only. Compressing scanned supporting documents to 2MB means the whole application packet uploads without hitting a mysterious size error.
Gmail caps at 25 MB, Outlook (with default settings) at 20 MB, Slack free at 1 GB. Sending a scan-heavy PDF over any of these means compressing first, because the file straight from the scanner often blows past all three.
Hiring portals routinely cap CV uploads at 2-5 MB. If your resume PDF is heavier because of embedded imagery, background graphics, or an ATS-scanned version, compressing to 2MB keeps the design intact while fitting the upload rules.
A folder of scanned contracts, receipts, or reference material grows to gigabytes over years. Batch-compressing everything to 2MB preserves readability while cutting archive storage 60-80% — worth doing before a major cloud backup or an office move.
WhatsApp caps document attachments at 100 MB; some countries\' regional versions much lower. Compressing scanned documents to 2MB is often the difference between "sends immediately" and "delivery failed."
