Document Workbench — Somu & Associates

Tool 01

Merge & Reorder PDFs

Add PDFs in the order you want them combined. Drag rows to reorder — the output follows the sequence shown below, no need to remember file names.

Add PDFs

Click to add PDFs or drag & drop here
Add them one at a time or select several — they'll queue in the order added
ℹ️Tip: for interleaved order, all files should ideally have the same page count — extra pages from a longer file are appended at the end.

Tool 02

Compress to a Target Size

Shrink PDFs, scans, or photos down to a KB / MB size you specify. Each file is compressed independently and the closest achievable size is shown before download.

Add files

Click to add PDFs or images or drag & drop here
Accepts PDF, JPG, PNG
ℹ️Note: compressing a PDF re-renders each page as an image to reduce size — great for scanned documents, but the resulting text is no longer selectable/searchable. The exact target size is best-effort, not guaranteed to the byte.

Tool 03

Enhance Documents & Photos

Sharpen faint scans, lift contrast, and upscale resolution. Optionally target a final file size, same as the compress tool.

Add files

Click to add PDFs or images or drag & drop here
Accepts PDF, JPG, PNG
ℹ️Honest limitation: this sharpens, upscales and cleans contrast using standard image processing — it cannot reconstruct detail that genuinely isn't in the original scan the way AI photo-restoration tools claim to. Best for faint, low-contrast, or slightly blurry scans.

Tool 04

PDF → Image → PDF

Rasterize a PDF to images and rebuild it into a PDF, in one step — no downloading images and re-uploading them separately.

Upload PDF

Click to add a PDF or drag & drop here
Each page is rasterized to an image, then rebuilt into a single PDF automatically
ℹ️Output pages become images, so text is no longer selectable/searchable — same trade-off as the Compress tool, useful for flattening or standardizing a scanned document.

Tool 05

Transparent PNG

Pick a colour on your image — the background, usually — and turn it transparent. Click the preview to sample the colour straight off the image, or set it manually.

Upload image

Click to add an image or drag & drop here
JPG or PNG — output is always PNG (needed for transparency)
#ffffff
ℹ️Works best on flat, fairly uniform backgrounds (solid colours, simple gradients). Busy or textured backgrounds may need a higher tolerance and can catch bits of the subject too — increase tolerance gradually and watch the preview.
