AI detection looks at
signals, not verdicts.
We calculate a reference score from sentence length, repeated connectors, and stylistic consistency. This is not an authorship or plagiarism test. A configured server model is optional and requires per-request consent.

04 / IMAGE SIZE
Make an image smaller
Make an image smaller
without uploading it.
Your browser re-encodes the picture on this page. Choose a quality, optionally cap the width, and compare the real before and after sizes. If re-encoding would make the file bigger, we say so and hand back the original.
05 / FILE SIZE

Bundle files into a ZIP
and see the real saving.
The archive is built in this page. Text, CSV, logs, and BMP files shrink a lot. Files that are already compressed — JPEG, PNG, MP4, PDF, DOCX — barely shrink at all, and this tool reports that honestly instead of showing an invented number.

How it works
Reduce complex document work
to three steps.
Inputs and results stay in one surface, so you spend less time switching windows or installing software.
- 01
Choose a tool
Select documents, AI writing signals, or character count based on what you need right now.
- 02
Add a file or paste text
Drop a file into the workspace or paste your writing to process it in the browser.
- 03
Review the result
Save a PDF, review the reference score, or use the writing metrics for your next step.
Document Forge principles
Explain the process
before the result.
Reference analysis
AI-style results are statistical writing signals for reference. They do not confirm who wrote a text.
Search to use
Visitors arriving from search can use the tool immediately and connect the result to a clear next action.
Choose by outcome
A file type is not a workflow.
Viewing, converting, counting, checking, compressing, and bundling each have a different “done” state. Start with the result you need, then verify the output before you share it.
Need to read a PDF?
Open the existing file in the browser viewer. Re-converting it only adds another chance for layout changes.
Need a PDF from HWP, HWPX, or text?
Preview the rendered output, use the print dialog deliberately, and reopen the saved PDF to check page breaks.
Need a writing or length check?
Use signals and counts as editing information, then confirm the destination's own rules and keep the draft history.
Need a smaller or shareable file?
Measure image compression or ZIP output from your actual files. Already-compressed formats may not shrink.
Practical guides
Answers before
the next deadline.
Short, original guides explain what each format can do, what this browser tool does not claim, and the safest next step. Every guide is written for this site and states its own limits.

Check these details
before you start.
Can I convert an HWP file to PDF?
Yes. Supported HWP files are rendered in this browser and opened in a print-ready PDF save view. Fonts and complex layouts can differ, so check the saved PDF before sharing.
Can I trust the AI writing score?
The score is a reference metric built from writing patterns such as sentence length and repetition. It does not identify an author or determine plagiarism, so use it as one input before submitting work.
Are my files or text stored?
Document conversion stays in your browser and does not upload your file. The optional server model sends pasted text only after you consent. Read the privacy noticefor the current boundary.
Is Document Forge free or does it need an account?
Browser tools are free with no sign-up. The optional server model has a small daily allowance and stops when that limit is reached; there is no paid checkout, subscription, or overage billing.
Which file types can the browser handle?
HWP, HWPX, TXT, Markdown, and HTML are handled in the page, while existing PDFs open in the browser viewer. Read the format guide.
How much smaller can an image get?
A photo straight from a phone or camera usually drops 60 to 90 percent at quality 75, and converting to WebP saves more again. An image that is already optimised may not shrink at all. The tool measures the actual result and hands back the original if re-encoding would make it bigger. Read the image guide.
Why did zipping my files barely save anything?
Because they were already compressed. JPEG, PNG, MP4, MP3, PDF, DOCX, XLSX and HWPX all contain compressed data, so a ZIP has almost nothing left to remove. ZIP still helps for text, CSV, logs, BMP and SVG, and for bundling many files into one download. Read the file size guide.
