FILE_TOO_LARGE

FILE_TOO_LARGE

Error message

The PDF is larger than paperreview.ai's 10MB limit.

What it means

readPdfFile() enforces MAX_PDF_BYTES (10 * 1024 * 1024 = 10MB). If the file's size exceeds 10MB it throws FILE_TOO_LARGE before uploading, because paperreview.ai will not accept PDFs beyond its 10MB limit.

Solutions

1. Compress the PDF (e.g. Ghostscript: gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -o out.pdf in.pdf)
2. Downsample or recompress figures to JPEG at reasonable DPI before rebuilding
3. Remove embedded attachments/animations or unused fonts from the LaTeX build
4. Split or reduce supplementary material and submit only the main paper

Example fix

// before
await readPdfFile('./paper-30mb.pdf');
// after
// $ gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -o paper-small.pdf paper-30mb.pdf
await readPdfFile('./paper-small.pdf'); // under 10MB

import fs from 'node:fs';
const MAX_PDF_BYTES = 10 * 1024 * 1024;
function assertPdfSize(p) {
    const size = fs.statSync(p).size;
    if (size > MAX_PDF_BYTES) throw new Error(`${p} is ${(size / 1048576).toFixed(1)}MB; compress below 10MB first`);
    return size;
}

function isWithinUploadLimit(p) {
    try { return fs.statSync(p).size <= 10 * 1024 * 1024; } catch { return false; }
}

try {
    const pdf = await readPdfFile(userPath);
} catch (e) {
    if (e?.code === 'FILE_TOO_LARGE') {
        console.error('Compress first: gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -o small.pdf ' + userPath);
    } else throw e;
}

When it happens

Trigger: Calling readPdfFile() on a PDF whose fileStat.size > 10485760 bytes — e.g. papers with high-resolution figures, embedded fonts, or scans saved without compression.

Common situations: Camera-ready PDFs with 300dpi+ embedded images; LaTeX builds including full vector datasets; scanned manuscripts; arXiv source downloads with large supplementary figures.
