Why choose iFillPDF
Live preview on your own page
Move the top, bottom, left and right sliders and the preview re-renders immediately, so you set the crop against your actual document rather than guessing at millimetres.…
Sliders or a shape preset — applied to every page
Either set the four margins yourself, or pick A4 portrait, US Letter or square and let the page be centred and trimmed to that shape.…
Quality preserved
No compression — the kept area retains its original sharpness.
Local processing
Files never leave your computer — processed in your browser.
Technical details
Trim white margins, drop scanner-edge artifacts and reset the visible page box on every page of a PDF with a real live preview — useful for tightening up a 600 dpi flatbed scan of an IRS Form 8821 before filing, removing Companies House CS01 footers before redistribution, normalizing Hetzner-printed invoices, prepping ISO 19005 PDF/A-2 archive masters, or reformatting a real-estate purchase agreement to fit a court-admissible 8.5x11 in. binder. Two ways to set the crop: four margin sliders — top, bottom, left and right, 0 to 200 points in 5-point steps — or a shape preset that centres the page on A4 portrait, US Letter or a square. Both apply the same crop to every page in the document, with a live preview updating as you drag. Be clear on what is missing: there is no automatic margin detection, no content-bounding-box analysis and no per-page adjustment, so a stapled packet whose pages were fed through the scanner at slightly different angles needs one pass per group of pages. Output keeps the original page content, fonts and images untouched — only the page boxes are rewritten, never the underlying content stream, so nothing is re-compressed and nothing is re-rendered. Unlike Adobe Acrobat ($19.99/mo Pro plus mandatory Adobe ID sign-in even for the "free" online cropper, US infrastructure under Cloud Act 50 USC §3024), Smallpdf (2 free tasks/day cap then $9/mo Pro), iLovePDF (free but ad-laden, Spanish servers), PDFResizer (free with auto-crop but no per-page control), VisualPDF, DeftPDF or FreeConvert: WebAssembly local processing runs entirely in your browser — no signup, no watermark, no upload to any server, your file never leaves your device. ICO UK registered, GDPR Art. 5(1)(c) data minimization compliant.

How does iFillPDF compare to iLovePDF, Adobe Acrobat, Smallpdf and PDFResizer for cropping a PDF?+
Four hard differences: (1) Pricing — iLovePDF crop is free but ad-laden with a 25 MB cap on the free tier; Adobe Acrobat Pro is $19.99/mo with a mandatory Adobe ID sign-in even for the "free" online cropper; Smallpdf gates real cropping behind Pro at $9/mo (or $108/yr) after a 2-task/day free cap; PDFResizer is free with an auto-crop button but no per-page manual control. iFillPDF is free, unlimited, no signup, no card, no upload to any server. (2) Privacy — iLovePDF uploads your file to Spanish servers; Smallpdf uploads to Switzerland (outside EEA, no automatic GDPR adequacy); Adobe processes on US infrastructure under Cloud Act 50 USC §3024 and FISA 702 reach; PDFResizer hosts on shared US infrastructure. iFillPDF runs WebAssembly entirely in your browser — your file never leaves your device, GDPR Art. 5(1)(c) data minimization compliant, ICO UK registered. (3) Per-page control — Adobe Acrobat Pro ($19.99/mo) is the one that genuinely does it; iFillPDF, PDFResizer and Smallpdf free all apply a single crop to every page, and iLovePDF makes you fight a multi-step UI for it. PDFResizer also has automatic margin detection, for that workflow. (4) Standards preservation — Adobe rewrites the page content stream, which can invalidate a digital signature embedded in the file; Smallpdf flattens transparency layers; iFillPDF rewrites only the page-box dictionaries, leaving wet-ink scans, embedded ESIGN Act 15 USC §7001 signatures and PDF/A-2 archive metadata cryptographically untouched.
