Squishly is a free collection of file tools for images, PDFs and video, built to run in your browser rather than on someone else's server.
DOCUMENTS. Compress a PDF with Quick or Deep mode, or set an exact target size such as 100 KB or 1 MB โ useful when an upload form imposes a limit. Text stays selectable. Organise pages on a single canvas: merge several PDFs into one, split a document into separate pages, drag to reorder, and rotate or delete individual pages. Convert PDF pages to JPG or PNG, and add a text or image watermark with either a quick centred stamp or full drag-and-resize control on every page.
IMAGES. Compress JPG, PNG and WebP individually or in batches, or compress to an exact target size. Convert between formats with quality control. Resize and crop, split an image into a grid of tiles, or build a collage or photo mosaic. Remove backgrounds in one click on your device, with an HD mode for studio-quality edges. Recolour a single colour while keeping natural shading, extract text from photos and scans with OCR, and turn images into a PDF.
VIDEO. Compress clips, convert between MP4, MOV and WebM, trim to just the part you need, export to GIF, and recolour footage โ all on your own device.
AI DOCUMENT TOOLS. Summarise a PDF, Word or PowerPoint file into clear key points, translate a document, or ask questions and get answers drawn straight from the file. These run server-side and use credits.
The everyday tools run entirely in your browser using WebAssembly, so files are never uploaded. No queue, no upload size ceiling, no watermark on the result and no sign-up required. Every output comes with a short report showing original versus final size, dimensions and quality, so you can see exactly what was traded away.
Free to use, with a Pro plan for higher limits and monthly AI credits. Any free tool can also be embedded on your own website at no cost. The whole site is available in English and Arabic, including right-to-left layout and Arabic OCR.
React Engine SquishlySquishly's answer:
Three things.
Breadth: images, PDFs and video in one place, plus AI document tools. Most free alternatives do only one of those, so people end up bouncing between sites.
Where the work happens: the everyday tools โ compress, convert, resize, merge, split, watermark โ run entirely in your browser using WebAssembly. The file is never uploaded, which also means no queue and no server-imposed size cap.
Honesty about the result: every output with suitable tools comes with a short report showing exactly what changed โ original vs final size, dimensions, quality โ so you can see what you traded away instead of guessing.
Squishly's answer:
People who need one file job done quickly, without installing software or creating an account.
In practice: students and job applicants fighting upload limits on portals ("PDF must be under 100 KB"), freelancers and small businesses preparing documents and product images, and office workers who can't install desktop software on a managed machine.
There's also a distinct Arabic-speaking audience across the Gulf and wider MENA region โ the site is fully localised, which most competitors in this space are not.
Squishly's answer:
Most free file tools are single-purpose: a PDF site, an image site, a video site. Squishly covers all three, plus AI document work โ summarise, translate, or ask questions about a document โ so one bookmark replaces several.
Beyond that: no sign-up to use the free tools, no watermark on the output, no waiting queue, and no upload size ceiling, because for most tools nothing is uploaded at all.
It's also fully bilingual โ English and Arabic with proper right-to-left layout, including Arabic OCR โ which is rare in this category.
Squishly's answer:
I build and run Squishly on my own.
It started from a small annoyance: to make a file smaller you usually have to upload it to a stranger's server, wait in a queue, and then find a watermark on the result โ or be asked to create an account first. For a private document, that's a lot to accept for something the browser can already do by itself.
So I built the opposite. The file stays on your device wherever possible, every result shows honestly what changed, and the everyday tools stay free with no watermark and no sign-up. Server-side and AI features exist where a server is genuinely needed, and they're clearly labelled.
Being independent is also why it's bilingual in English and Arabic from the start, with proper right-to-left layout โ not added later as an afterthought.
Squishly's answer:
The front end is React with TypeScript and Tailwind CSS.
The interesting part is client-side: the heavy processing runs in the browser via WebAssembly. That's what makes it possible to compress, convert and edit without uploading โ video encoding, PDF manipulation, OCR and background removal all run on your own device.
Accounts and payments use established third-party providers rather than anything home-grown, and the site is bilingual end to end.
Squishly's answer:
Squishly is a free consumer tool used by individuals and small teams rather than named enterprise accounts, so we don't publish a customer list.

I was wondering to use paypal's React Engine (https://github.com/paypal/react-engine), but I have some doubts:. Source: over 4 years ago
