PDFStay vs iLovePDF: Why PDFStay Is Better for Private PDF Compression

Why pay more to send an ordinary PDF to a remote service?

PDFStay is built for people who want a focused PDF task without an unnecessary server upload or an expensive recurring plan. For supported ordinary tasks, your PDF stays in the current browser session; PDFStay's observed monthly price is 40.2% lower; and you can inspect published input and output examples before choosing it.

PDFStay wins on the three things that matter most for everyday private compression: where the file is processed, what the service costs, and whether the claimed result is backed by a direct example.

• No ordinary file upload to PDFStay servers: the browser reads and processes the PDF locally for supported tasks.
• Three free compression modes: one PDF up to 25MB can use standard, image, or scanned-PDF compression.
• Published compression examples: fixed first-party fixtures recorded reductions of 48.33%, 81.74%, and 91.26% in the stated Chromium environment.
• Lower observed monthly price: PDFStay's $2.99 monthly option is 40.2% below iLovePDF's observed $5 monthly price; PDFStay also publishes a $1 24-hour pass and a $12.99 Lifetime option.
• No registration for basic tools: start a small everyday PDF task without creating an account.
• Results return to your device: the completed PDF downloads from the same browser session.

Real PDFStay examples: up to 91.26% recorded reduction

PDFStay publishes first-party compatibility measurements for fixed, non-sensitive fixtures tested in Chromium 148 on July 12, 2026. These are direct examples, not promises for every document and not an independent product ranking.

Direct example: the published scan-style fixture went from 2,141,091 bytes to 187,107 bytes while the page count remained 2 → 2. A different scan may produce a different reduction or visual result.

Keep ordinary PDF content in your browser—not on our servers

According to the PDFStay privacy policy, ordinary PDF content is read and processed in the current browser session and is not sent to PDFStay servers. Temporary previews and results may remain in browser memory during the session, and the result is saved back to the device.

iLovePDF's public security page describes cloud infrastructure together with data retention and removal, encryption, internal controls, GDPR-related protections, and ISO/IEC 27001 certification.

For an everyday personal, financial, work, or scanned document, PDFStay removes a remote document-processing step from the supported workflow.

Choose PDFStay when you want privacy, proof, and a lower price

• You need to merge PDFs, split a PDF, or compress a scanned PDF under the same published local-processing model.
• You want a short paid option instead of immediately starting a recurring subscription.

PDFStay's current limitations

PDFStay is intentionally focused, and that creates real trade-offs:

• Fewer tools today: PDFStay currently offers fewer tools than iLovePDF. Its strongest fit is supported everyday browser-based tasks, not every conversion, editing, signing, mobile, desktop, or business workflow.
• A defined free limit: free compression covers one PDF up to 25MB; larger files, batch work, advanced scan settings, and custom naming require Pro.
• Device-dependent performance: because supported work runs locally, speed and memory use can vary by device and browser. Very large or complex PDFs may take longer or be a poor fit for browser processing.
• No fixed compression result: published fixture reductions are direct examples, not guarantees for every document or visual-quality target.

PDFStay will continue to be updated. Planned features are not presented as available, and no unconfirmed release dates are promised.

When iLovePDF may still make sense

iLovePDF may still fit organizations that specifically require its documented ISO/IEC 27001 certification, organizational security controls, or a broader service spanning web, mobile, and desktop. It may also suit users who need conversion, editing, signing, or business workflows that PDFStay does not currently provide.

For users focused on a supported everyday browser-based task, PDFStay's local-processing boundary, lower observed monthly price, and published examples remain the more relevant advantages.

How to compress one PDF with PDFStay
