Image & PDF Tools
Compress images, resize photos, reduce PDF file size, and convert formats with secure processing, automatic cleanup, and plan-aware limits.
Built for real upload and publishing work
Slim Files is designed for the practical jobs that create file bottlenecks: compressing oversized images before publishing, reducing PDF size for forms and portals, combining scans into a single document, and converting assets into the format a workflow actually needs.
Instead of treating every file as trusted browser metadata, the app validates uploads by content before processing begins. That keeps the experience cleaner for users while making the service more reliable for teams that need repeatable results, plan-aware limits, and predictable cleanup.
The goal is simple: help you get smaller, cleaner, more shareable files without introducing a complicated desktop workflow just to handle common image and PDF tasks.
Validated before processing
Uploads are checked by content so the workflow is driven by detected file type, not by extension alone.
Processed with plan-aware limits
Free, Pro, and Business accounts follow the same server-side rules for size, rate, and retention.
Cleaned up automatically
Temporary files are purged on a schedule so the app stays focused on short-lived processing jobs.

Open workflowPick the workflow that matches the job you actually need to finish
Most visitors are not looking for a general-purpose file lab. They are trying to solve one practical problem quickly: make an image smaller, resize a product photo, convert a WebP for reuse, compress a PDF for a portal, or merge a stack of images into a document. These shortcut links make those common paths easier to discover from the homepage and give crawlers a clearer map of the product structure.
Compress images before upload
Shrink large JPG, PNG, and WebP files before publishing to a CMS, sending them in email, or listing products on a storefront.
Resize images for exact dimensions
Prepare website banners, marketplace product photos, and social media visuals without switching to desktop editing software.
Convert formats cleanly
Move between JPG, PNG, and WebP when a platform or workflow needs a specific output type or transparency behavior.
Reduce PDF size for forms and portals
Make image-heavy PDFs easier to upload to job portals, intake forms, tax systems, and email clients with tight attachment caps.
Combine images into one document
Turn photo scans, receipts, and screenshots into a single PDF that is easier to submit, archive, or forward.
Extract PDF pages as images
Break a PDF into JPG pages when you need previews, social-ready assets, or a quick way to reuse individual pages.
Teams, creators, and everyday document work
Slim Files is a strong fit for marketing teams preparing lighter web assets, operations teams handling form and portal uploads, sellers standardizing marketplace images, and anyone who needs to make files easier to send without learning a new toolchain first.
Common tasks people search for most
Some visitors arrive looking for a named tool, while others search for a very specific task such as compressing a JPG, shrinking a PDF for an upload limit, or resizing an image for a platform. These direct page links make those routes easier to find and strengthen the internal path between the homepage and the task-focused landing pages.
Built as a product and a reference site
Slim Files now includes public support and policy pages, a service overview, an About page, and a growing guides section that explains the choices behind file workflows instead of assuming every visitor already knows the right settings.
That matters because good file handling is rarely just one button. People often need help choosing a format, understanding quality tradeoffs, or deciding whether a PDF should be compressed or rebuilt. The site is being shaped to answer those questions more directly.
