Reduce PDF file size by up to 70% free — no file size limit, no sign-up, no watermark. Choose Light, Medium, or Heavy compression. Text stays perfectly sharp at every level because PDF text is stored as vector data, not pixels. The compression engine runs locally in your browser — your documents never leave your device, and there is no artificial cap on how large a PDF you can compress.
To compress a PDF free with no size limit, choose a compression level and let it process in your browser — no sign-up or upload required. On ihatepdf, upload your PDF (large files welcome), pick Light, Medium, or Heavy compression, and download a file up to 70% smaller. Text stays perfectly sharp and your document never leaves your device.
Job application portals and applicant-tracking systems frequently cap CV and resume uploads at 1–2MB, and a single high-resolution photo or designed template can easily push a one-page CV over that limit. Compressing your CV PDF fixes this in seconds without re-exporting from Word or a design tool. Upload your resume, choose Medium compression (or Heavy for the strictest portals), and download — the text stays perfectly sharp so recruiters and automated screening systems read it without issue. Because everything runs locally, your CV with all its personal details is never uploaded to any server.
Many free online compressors silently cap uploads at 10–50MB or throttle large files behind a paywall. ihatepdf has no artificial size limit because it does not upload your file at all — compression runs inside your browser tab, so the only real limit is your device memory. This makes it ideal for compressing scanned books, high-resolution presentations, multi-hundred-page reports, and other heavy PDFs that hosted services reject. For extremely large documents, close other browser tabs first to free up RAM, or split the PDF into sections, compress each, and merge them back.
Need to hit an exact upload limit? Use the size-targeted compressors — each tuned for that limit, all free with no upload:
Large PDFs get rejected by email providers, fail to upload to job application portals and government forms, slow down document sharing, and consume unnecessary cloud storage. Gmail blocks attachments over 25MB, Outlook caps at 20MB, and many HR portals and government forms enforce 2–5MB limits. Compressing removes redundant data, optimizes embedded images, subsets fonts, and strips hidden metadata — shrinking the file dramatically while keeping the visual content intact. Text quality is never affected at any compression level.
Most online PDF compressors — ilovepdf, smallpdf, Adobe Acrobat online — upload your file to their servers to process it. For sensitive documents like CVs, contracts, medical records, and financial statements, this creates unnecessary privacy exposure. ihatepdf runs the entire compression pipeline inside your browser tab. Your file bytes never reach any server — not even ihatepdf's. The tool also functions completely offline: once the page loads, disconnect your internet and it still compresses perfectly.
Six optimizations run together: (1) Image downsampling — each image is resampled to the target DPI, computed from the size it is actually drawn at on the page rather than guessed; (2) Measured re-encoding — every image is encoded several ways (JPEG, Flate, an indexed palette, CCITT G4 for scanned pages) and whichever comes out smallest is kept; (3) Font subsetting — embedded fonts are trimmed to only the characters used in the document, often a few dozen glyphs out of several thousand; (4) Font conversion — legacy Type 1 fonts are rebuilt as CFF, which stores the same outlines far more compactly; (5) Stream recompression — every stream is recompressed at maximum effort and byte-identical objects are shared; (6) Cleanup — metadata, thumbnails and unreachable objects are dropped. Text and vector graphics are never rasterized.
To compress a PDF under 1MB: use Heavy compression. For most image-heavy PDFs this is achievable in one pass. To compress for email under 25MB: Medium compression handles the vast majority of files. To meet government portal limits of 2–5MB: start with Heavy compression. If still too large, use the Split PDF tool to divide the document into smaller sections and compress each section separately. A 15MB scanned document typically becomes 2–3MB on Heavy compression.
Scanned documents compress 50–70%. Presentation PDFs with photos compress 40–60%. Text-heavy CVs and reports compress 10–30% since text is already stored as vectors. A 10MB scanned document typically becomes 2–4MB on Heavy compression.
Never. Text in PDFs is stored as vector data — it is completely unaffected by compression. Only raster images (photos, scanned pages, illustrations) are optimized. Text stays perfectly sharp at every compression level.
Choose Heavy compression. If still over 1MB, the PDF has many high-resolution images. Split it into sections using the Split PDF tool, then compress each part individually.
Gmail limits attachments to 25MB. Outlook to 20MB. Most HR portals cap uploads at 2–5MB. Use Medium compression for most cases. Switch to Heavy if the file is still too large.
No. Everything runs locally in your browser using WebAssembly. Your PDF never reaches any server. The tool also works fully offline once the page has loaded.
No artificial limit. The practical constraint is your device RAM — typically 100–150MB on desktop browsers. For very large PDFs, close other tabs to free up memory.
Not directly. Remove the password first using the Remove Password tool, compress it, then re-encrypt using the Encrypt PDF tool if needed.
Light (20–30%) resamples images to 300 DPI — ideal for professional printing. Medium (40–50%) targets 150 DPI — perfect for screen viewing and sharing. Heavy (60–70%) targets 72 DPI — maximum size reduction for archiving or portal uploads.
Adobe Acrobat uploads your file to Adobe servers and requires a paid subscription. ihatepdf runs entirely in your browser — no upload, no account, no subscription. Completely free.
There is no artificial limit. The only constraint is your device RAM — typically 100–150MB on desktop browsers. Unlike most online compressors that cap free uploads, ihatepdf processes locally, so large PDFs are handled directly on your machine. Close other tabs to free memory for very large files.
Upload your CV PDF, choose Medium compression (Heavy if the portal limit is strict, like 2MB), and download. Most CVs with a photo or design compress 30–60%. Text stays crisp so recruiters and applicant-tracking systems read it perfectly — and your CV is never uploaded to our servers.
Yes. ihatepdf never asks for an email, account, or sign-up. Open the page, compress, and download. There is nothing to register and no usage quota.
