Does compression require uploading my PDF?

No. This runs in your browser using WebAssembly; the PDF file isn’t uploaded to an external server. Once the tool is loaded in the browser, you can actually compress PDF files even without an internet connection.

Will compressing make the PDF unsearchable?

No. PDF text is vector data (this includes lines, curves, and font data), and thus stays sharp and searchable regardless of how much compression is applied. Only embedded images are compressed. However, if you choose ‘aggressive’ mode, these layers are flattened and re-encoded as images, so text will no longer be searchable.

Why is my compressed PDF sometimes larger than the original?

This happens when the original file contains heavily compressed images or mostly text with few images. In such cases, there would be little to strip, and the added overhead of re-encoding would typically result in a larger output file than the original.

What does the compression level setting actually change?

Low cleans up the internal structure, or removes unnecessary data. Medium level strips metadata like author name and rebuilds the file into a more compact binary format. High resaves images at a lower quality, usually at 30% - you’ll see more pixelated photos using this preset.

Can I compress a password-protected PDF?

No. ConvertYard cannot read or write encrypted PDFs. You must first use the Unlock PDF tool to remove the PDF password before you can use this tool to compress it.

How does target-size mode differ from the compression level slider?

Target-size mode will run the compression up to six passes automatically. It first runs the structural cleanup pass, then slowly lowers image quality from 80 to 30%, only stopping when the target size is met. Use this option if you have a hard limit (for example, an email attachment or a government portal).

LinkedIn says my resume is too large — what size does it accept?

LinkedIn caps resume uploads at 1 MB. The most common culprit is an embedded high-resolution photo or a background image. Compress to 1 MB here, or remove the photo from your PDF template before exporting.

Does compressing a resume PDF to 1 MB affect ATS parsing?

No. ATS systems parse text layers, not images. Compression only affects embedded images and metadata. As long as your resume is a real PDF (not a scanned image of text), compression will not change how an ATS reads your name, skills, or employment history.

What is the Schengen visa portal file size limit exactly?

There is no single limit — each member state runs its own visa portal. German consulates typically allow up to 2 MB per file; French consulates often cap at 1 MB. Compressing to 1 MB covers the strictest common case and keeps total application packages well within the overall upload cap.

I have a 12-page report. Is 1 MB enough to keep it readable?

For a text-heavy 12-page report generated as a PDF, 1 MB is generous — you may need no compression at all. Scanned documents at 300 dpi across 12 pages typically start around 8–15 MB and compress to 1 MB with visible but acceptable quality reduction on photos.

Can I compress a password-protected PDF?

No. ConvertYard cannot read or write encrypted PDFs. You must first use the Unlock PDF tool to remove the PDF password before you can use this tool to compress it.

1 MB is the inflection point where document size expectations shift from portal-enforced limits to social conventions. Resume uploads on LinkedIn, Naukri, and Indeed are routinely rejected or warned above 1 MB. Schengen visa applications have a soft 1 MB per-document expectation that speeds processing and avoids rejection at consulate portals. And many corporate environments still operate on the mental model that email attachments should be under 1 MB. The compressor targets 900 KB–1 MB, giving you maximum quality at the limit.

When do you need 1 MB?

Resume and CV uploads on LinkedIn, Naukri, Indeed. Job platforms enforce or warn above 1 MB on uploaded CVs to keep recruiter download times fast. LinkedIn explicitly caps resume uploads at 1 MB.
Email attachments for conservative recipients. Government offices, banks, and older corporate environments often have informal norms or hard server limits around 1 MB per email attachment.
Project documentation submissions. University project reports, tender bid documents, and client-facing proposals are commonly capped at 1 MB by submission form validators.
Schengen visa supporting documents. German, French, and Dutch consulate visa portals recommend individual documents under 1 MB to avoid upload errors and processing delays.
Health insurance claim documents. Digital claim portals for ICICI Lombard, Star Health, and similar insurers often apply a 1 MB per-document ceiling during online claim submission.
