Free tools for PDF, image and spreadsheet files

Shrink a PDF: downsample and recompress oversized images, then rewrite with compressed object streams. Never returns a bigger file than you gave it.

Remove the pages you list, e.g. 2, 5-7, last; everything else is kept in order.

Save every embedded image at its original quality (JPEGs byte-for-byte); duplicates are saved once.

Pull the text layer out of a PDF as plain text or per-page JSON (scanned pages need OCR).

Turn JPG, PNG, WebP and other images into one PDF, a page each; JPEGs are embedded without re-compression.

Pages and sizes, version, encryption and permissions, metadata, fonts, images, forms, scripts and text layer.

Combine several PDFs into one, in the order given, with a bookmark for each file.

Change a PDF's title, author, subject and keywords, or strip all metadata before sharing it.

Reorder, select or duplicate pages: write the new order, e.g. 3, 1-2, 5-last.

Number pages with your own format (e.g. 'Page 3 of 12'), position, start number and pages to skip.

Encrypt a PDF with AES-256: a password to open it, and optional limits on printing, copying and editing.

Rebuild a damaged PDF's structure (cross-reference table, broken objects) so it opens again.

Rotate all or selected pages by 90, 180 or 270 degrees clockwise, without re-rendering.

Split a PDF into several files: by page ranges, every N pages, or one file per page.

Render pages to PNG, JPEG or WebP at the resolution you choose (72-600 dpi).

Remove a PDF's password when you know it. Lifting printing, copying or editing limits needs the owner password.

Stamp text such as CONFIDENTIAL or DRAFT on every or selected page: centred, in a corner, or tiled.

Brightness, contrast, saturation, sharpness, blur, auto-contrast and greyscale, keeping transparency.

Make images smaller for the web or email: smarter encoding, optional resizing, or a target size in KB. Never bigger than the original.

Convert between JPG, PNG, WebP, AVIF, GIF, TIFF and BMP, keeping animation and colour profiles where the format allows.

Cut an exact pixel area, or crop to a ratio such as 16:9, 1:1 or 4:5 keeping the part you choose.

Make a complete favicon set from one image: favicon.ico, Apple touch and Android icons, and site.webmanifest.

Format, size, colour mode and profile, transparency, animation, DPI, and the camera and GPS data a photo carries.

Resize by pixels or percentage: fit inside a box, fill and crop to it, pad to exact dimensions, or stretch.

Rotate by any angle (right angles are pixel-exact) and flip; phone photos are first turned the right way up.

Remove location (GPS), camera, date and software details before sharing. JPEG, PNG and WebP keep their exact pixels.

Add a text or logo watermark to many images at once: position, size, opacity, angle, or tiled across the image.

Tidy a spreadsheet in one pass: trim stray and invisible spaces, fix numbers stored as text, drop empty rows and columns, remove duplicates, tidy column names.

Find every difference between two versions of a spreadsheet: added, removed and changed rows, cell by cell, in a highlighted workbook.

Convert between Excel (.xlsx, .xls, .xlsb), OpenDocument, CSV, TSV and JSON, keeping numbers, dates and codes such as 00123 exactly as they are.

See what is inside a spreadsheet: every sheet (hidden ones too), rows, columns, column types and empty cells, and a CSV's encoding and delimiter.

Combine spreadsheets or sheets into one: stack their rows with columns matched by name, or gather them as the sheets of one workbook.

Understand a dataset in seconds: each column's type, blanks, distinct values, ranges, averages, most common values, and problems such as numbers stored as text.

Split a spreadsheet into several files: every N rows, one per value of a column (say, one per region), or one per sheet.
