Frequently asked questions
Is this tool free?
Yes — free and unlimited. No account, no watermark, no per-file charge.
Which formats are supported?
Each tool lists the formats it accepts under the drop area. Image tools take JPG, PNG and WebP; PDF tools take PDF files, while JPG to PDF accepts JPG, PNG, WebP and HEIC.
Can I process several files at once?
Image compression, resizing and JPG to PDF take up to 50 files per batch and download together as a ZIP. Splitting, deleting pages, merging and extracting work on the files shown in the panel — one PDF at a time where the tool is single-document.
Are my files uploaded anywhere?
No. Every step runs in your browser, so files never leave your device — you can verify it in the network panel.
Will compression reduce quality?
Compression re-encodes JPG and WebP at the quality you choose, so some loss is expected below 100%; PNG stays lossless. Merged, split and page-deleted PDFs keep their original content, and PDF tools that render or re-encode images say so in the result panel.
What if 20KB is impossible?
We lower quality first, then dimensions, and stop at 64px on the shortest side. If it still doesn't fit, we return the smallest result with the real number and suggest switching format or raising the target.
