What you'll get: a tighter rewrite preserving every fact, ~40–60% of original length. Not a summary — the document itself, shorter. For another use, try AI · TL;DR (one-paragraph summary instead).

Why people use Condense PDF

Condense PDF cuts 40–60% of a document’s length while keeping every fact and conclusion intact. Different from summarize (which restructures into a digest) or improve-writing (which tightens 20–30%): condense is aggressive shortening that preserves the doc’s shape and substance.

Length-constrained submission
Op-eds with 1500-word limits, conference papers with strict page caps, application essays with character limits. Drop the over-length draft, get a tighter version that respects the constraint while preserving the argument.
Email-thread digest from long doc
Long internal docs (project briefs, post-mortems, RFC drafts) shared as email summaries. Condense produces the 40% version that fits in an email body without losing the substance.
Verbose draft tightening
Drafts that sprawled past their useful length — common with first-pass writing. Condense brings the doc back to a publishable length without you needing to do the painful self-editing pass.
Lecture notes → revision sheet
Detailed lecture notes condensed to revision-sheet length (one page per topic). Useful for exam prep where the full notes are too long to scan during revision.
Verbose policy doc shortening
Internal policy docs that ballooned over revisions. Condense produces the version that’s actually readable without losing the policy specifics.

How Condense PDF works

Three steps. Sign in to run, zero retention — files never persisted on our servers.

  1. STEP 1
    Drop the doc
    PDF up to 100 MB. Works on prose-heavy content; structured tables / code blocks pass through unchanged.
  2. STEP 2
    We rewrite shorter
    Server-side extraction, then a constrained rewrite that targets 40–60% length reduction. Every numeric value, named entity, and factual claim preserved verbatim. Repetition collapsed, transitions tightened, examples consolidated. Routing layer picks the model best at preservation-during-aggressive-cut.
  3. STEP 3
    Get the shorter version
    Markdown output, typically 50% of input length. Page citations link each condensed section back to the source for verification.

What makes pdfcraft ai different

  • Citations on every claim
    Every AI summary, answer, and translation links back to the page it came from. You can verify the source before relying on the output. Hallucination is bounded, not blind.
  • Pay only for what you use
    No subscription. Purchased credits never expire. Cancel anytime. Cost shown before you run — exact credit amount appears after upload.
  • Multi-provider routing, no vendor lock-in
    We balance multiple AI providers per call to optimise cost and quality. If one has an outage, the next call automatically tries another. You're not bound to a single vendor's pricing or downtime.
  • Zero retention by design
    Your PDF lives in memory only as long as the AI call needs it, then it's discarded — nothing is persisted to our servers. We don't fine-tune models on your data. Verifiable in your dashboard's audit log.
  • Honest about model limits
    When a doc exceeds the model's context window we surface that the output was truncated (we render result.wasTruncated in every AI tool's UI). When a number can't be verified from the source we flag it. No silent failures.

Frequently asked questions

How is this different from AI Summarize or Improve Writing?
Summarize restructures into a digest format (different shape than source). Improve Writing tightens 20–30% while preserving everything. Condense is aggressive 40–60% shortening preserving doc shape. Pick based on output goal: digest = summarize, polish = improve writing, aggressive cut = condense.
Are numbers and names preserved?
Yes — explicitly. Every numeric value, percentage, date, currency amount, name, and proper noun preserved verbatim. Aggressive shortening creates risk of meaning drift; we prioritize preservation of factual anchors.
What if 60% feels too aggressive?
Re-run; the model is non-deterministic so re-runs vary length within the 40–60% target band. For explicit length control (“exactly 1500 words”), trim manually after — the condensed output is a 60-90% complete starting point, not the final cut.
Will it preserve structure?
Headings + list structure preserved. Within sections, paragraphs may consolidate (two short paragraphs → one tighter one) but the doc’s skeleton stays.
What’s the credit cost?
3 credits per doc. Cost is fixed regardless of doc size.
What if the condense changes meaning?
Possible with aggressive cuts. Read the output before relying on it — page citations make spot-checking easy. For high-stakes content (legal, medical, technical specs), treat as a draft for human review, not a final cut.

Need the opposite (more depth)?

Expand PDF elaborates each bullet / sentence into fuller paragraphs with source-grounded context. Useful for converting a tight draft into a longer-form treatment.
