About ToolzStack
ToolzStack is a set of online tools for everyday file jobs: turning a PDF into an editable Word document, converting iPhone HEIC photos to JPG, merging or splitting PDFs, shrinking a video for email, or formatting JSON. Each tool page explains the formats involved, what the result will look like, and where your file is processed.
The main groups of tools and what they are for.
PDF to Word, Excel and PowerPoint with table detection and English OCR for scanned pages; Word, Excel, PowerPoint and images to PDF.
Merge, split, crop, rotate, reorder, flatten, protect and unlock PDFs. Files up to 50 MB are processed in your browser.
Convert JPG, PNG, WebP, HEIC, SVG and more, and resize, crop, rotate or enlarge pictures.
Convert between common formats, extract MP3 audio from video, and trim or crop clips.
Reduce the size of images, PDFs, videos, audio and Office documents with quality presets.
Format JSON, decode JWTs, test regular expressions, generate UUIDs and hashes. These run entirely in your browser.
From choosing a tool to downloading the result.
Search above by format or task, or filter by category. Each tool page lists what it accepts and what it produces.
Small image and PDF jobs run on your device and are not uploaded. Conversions that need software such as LibreOffice, FFmpeg or OCR run on our servers.
You get a new file; the original is not changed. Files on our servers are deleted automatically after the retention period in the Privacy Policy.
Jump into common format pairs or switch to a nearby tool when you need it.
Finding tools and getting help.
Type a format (for example "heic") or a task (for example "merge") in the search box to filter the list.
Use the category buttons above the list to show only image, document, media or developer tools.
Sign in and select the heart on a tool to keep it at the top of its category.
Use Report a Bug on any page, the Help Center, or the contact form if a conversion does not work as expected.
ToolzStack
An online toolkit for converting, editing and compressing files, plus developer utilities that run in your browser.
ToolzStack
One-off file jobs where installing desktop software is not worth it: a form that only accepts PDF, a photo that will not open, a file too large to email.
ToolzStack
Your original file is never changed; you download a new copy. Each tool page lists its limitations, such as layout changes in PDF to Word or colour loss in PNG to SVG.
Where supported, files are processed directly in your browser. Tools that need more advanced processing upload the file to ToolzStack servers, where an automated cleanup job removes it after processing.
Search for a tool above, or contact us if you cannot find what you need.
Common answers so you can keep moving.
Yes, you can use the tools without an account or payment. Server-side conversions count towards a monthly usage allowance; the paid plans on the Pricing page raise the allowance and file size limits and remove ads.
Developer tools never upload what you paste. Small JPG, PNG and WebP conversions and most PDF page tools (merge, split, rotate and similar, up to 50 MB) run in your browser. Office documents, PDF to Word, Excel or PowerPoint, audio, video and most other conversions are processed on our servers.
Files processed on our servers are kept only so that you can download the result, then an automated cleanup job deletes them. The Privacy Policy states the current retention period.
Not for conversions or developer tools. An account is needed to save favourites, see your recent conversions, send files with File Transfer, and manage a paid plan.
Check that the file opens on your device and is not password-protected or corrupted, then try again. If it still fails, use Report a Bug with the file type and the error message, or contact support.
Yes. Use the contact form and describe the format or task you need.
