Your files never leave your device
GramPDF shrinks PDFs to a size you choose, resizes images, merges and splits documents, and removes backgrounds. It is free, needs no account, and runs entirely in your browser.
Rasterize re-renders each page as a compressed image, which shrinks the most but makes text unselectable. Optimize only keeps sharp vector text and rebuilds the file structure, so quality is unchanged but savings are smaller.
PNG is lossless, so it can't be shrunk to a target size by lowering quality. Switch to JPEG or WebP, or use the quality slider.
Each image becomes one page, in the order shown. Use the arrows to reorder or the ✕ to remove one first.
Files are combined in the order shown, all pages included. Nothing is compressed or altered.
Output is a transparent PNG. The first use downloads a small AI model (about 40 MB, cached afterwards). Your photos are still never uploaded. Works best on photos with a clear subject.
Skip the ad-filled converters. Each tool below does one thing well and works offline once the page has loaded.
Reduce PDF file size for email, job portals and government forms. Pick a quality level or set a target such as 100 KB, 200 KB or 2 MB and GramPDF finds the settings that fit. Choose Optimize only to keep text sharp and searchable.
Compress a PDFResize photos by percentage, width, height or exact dimensions. Export as JPEG, WebP or PNG, and aim for a specific file size like 50 KB for application forms and ID uploads. Process a whole batch and download a single zip.
Resize imagesTurn JPG, PNG and WebP photos into one tidy PDF. Reorder pages, choose A4, US Letter or fit-to-image sizing, and set margins. Good for scanned certificates, receipts and signed forms.
Convert images to PDFExtract a page range like 1-3, 5, 8-10 into a new file, or save every page as its own PDF. Nothing else in the document changes.
Split a PDFCombine several PDFs into one document in the order you set. Pages are stitched together without recompression, so quality stays identical.
Merge PDFsCut out the subject of a photo and export a transparent PNG with no watermark. Handy for product shots, profile photos and passport-style edits. Runs an AI segmentation model on your device.
Remove a backgroundNo sign-in, no waiting in a queue, no upload progress bar.
Drop a PDF or photos onto the tool, or tap to pick them from your phone or computer.
Choose a quality level, a page range or a target size in KB or MB. Defaults work for most files.
Save each file or grab a zip. When you close the tab, everything is gone from memory.
Most online PDF tools send your bank statements, IDs and contracts to a server. GramPDF runs the work in your browser, so there is nothing to intercept, store or leak.

Many upload forms reject files above a fixed limit. Pick a preset to jump straight to the compressor with that target already set.
Yes. Every tool is free with no signup, no watermark and no daily limit. Processing runs on your own device, so there are no server costs to pass on to you.
No. Photos and PDFs are processed inside your browser and never leave your device. The one exception is background removal, which downloads a small AI model (about 40 MB, cached afterwards) the first time you use it. Your photos are still not uploaded.
Open the PDF compressor, drop in your file, choose Target a file size, enter 100 or 200 KB and click Compress PDF. GramPDF tries progressively stronger settings until the file fits under your target.
Rasterize re-renders each page as a compressed image, which gives the smallest file but makes text unselectable. Optimize only keeps real vector text and rebuilds the file structure, so quality is unchanged but savings are smaller.
Yes. In the image resizer choose JPEG or WebP, select Target size and enter the size in KB or MB. GramPDF searches for the highest quality that stays under your limit. PNG is lossless, so it cannot be shrunk this way.
Yes. GramPDF works in any modern mobile browser on Android and iOS. Very large PDFs may be slow on older phones because all processing happens on the device.
No. Cut-outs are exported as transparent PNG files with no watermark and no signup.
