Autotracer

Autotracer is a free web service that converts raster images into vector graphics that can scale. It accepts image formats including JPEG, GIF and PNG, and lists EPS, SVG, AI and PDF as outputs. Its upload field also lists JPG and PDF among supported file types. No registration or email address is required. Uploads can be up to 6 MB and 5000×5000 pixels. Before conversion, users can set the image to a palette of 1 to 256 colors, with smoothing, despeckling and white-background handling available as additional options. The service uses the autotrace library developed by Martin Weber and Java Advanced Imaging API for image preprocessing. Autotracer identifies logos, page layouts, type, line art and illustrations as graphics suited to vector format. Automatic tracing usually needs further post-processing. Submitted files and converted results are deleted after half an hour, and the site says it keeps no backups. Google AdSense may use cookies and web beacons for advertising.

Autotracer provides free browser-based raster-to-vector conversion with several output formats and image controls. Check the upload limits and expect that the result may need post-processing.

Autotracer suits people who need to turn raster artwork such as logos, type, line art or illustrations into vector files. It is available in a browser and requires no account.

Autotracer is a browser service for turning bitmap artwork into editable vector files. It fits occasional users handling logos, line art, type, layouts or illustrations who do not want an account. The trade-off is a useful but bounded converter: small uploads and expected cleanup make it less suitable for production-ready artwork.

Overview

Autotracer converts raster images into EPS, SVG, AI and PDF. Its documentation names JPEG, GIF and PNG as source formats, while the upload field accepts JPG, PNG, PDF and JPEG, so the field is the practical check before submitting a file. No registration or email is required, which keeps one-off jobs quick.

Files are limited to 6 MB and 5000×5000 pixels. Those limits accommodate ordinary web and design assets but can rule out large scans or high-resolution illustrations. Automatic tracing commonly needs further post-processing, so treat the download as an editable starting point rather than a finished logo or illustration.

Key features

Palette and cleanup controls

Before vectorization, you can set the color count from 1 to 256. Lower values can produce a simpler, potentially easier-to-edit trace; higher values retain more color variation at the cost of a more complex result. Smoothing and despeckling address rough contours and stray marks, while the white-background option can keep a plain backdrop from becoming part of the vector artwork. These controls improve the starting trace but do not replace manual cleanup.

Processing and formats

The service uses the autotrace library developed by Martin Weber and Java Advanced Imaging API for preprocessing. EPS, SVG, AI and PDF outputs cover common print, design and exchange workflows, although the amount of editing required will depend on the source image.

File handling

Submitted inputs and converted outputs are automatically deleted after 30 minutes, with no backups. Maklabu GmbH employees are the only people permitted access, and its policy says files are not inspected or mined for data. Operational logs retain IP address, access date and access type for less than a week, usually no more than three days, without an analytics system.

Pricing

Autotracer has one plan: Free online image vectorizer costs free. It includes browser access, 6 MB maximum uploads, 5000×5000 maximum dimensions and a 1–256 color range. There is no free trial because the service is already free, and no account, seat or renewal commitment is required. The donations page says it will remain free. This is a strong fit for infrequent conversions; users needing larger files or guaranteed finished artwork will need another workflow.

Platforms

Autotracer runs on the web, so it is available wherever a compatible browser is available rather than as a native desktop or mobile application.

Who it's for

Choose it for a quick, no-login conversion of a modestly sized logo, page element, type treatment, line drawing or illustration when you can inspect and refine the vector afterward. It is less appropriate for oversized source files, batch-oriented production, or work that must emerge print-ready without manual editing.

Pros and cons

Pros

• No account barrier: registration and email are not required for a one-off job.
• Useful output coverage: EPS, SVG, AI and PDF serve common vector workflows.
• Adjustable tracing: a 1–256 color range plus smoothing, despeckling and white-background handling gives meaningful control.
• Short retention: inputs and outputs are deleted after 30 minutes and are not backed up.

Cons

• Small upload ceiling: 6 MB and 5000×5000 pixels exclude some high-resolution sources.
• Editing remains likely: automatic tracing usually requires post-processing.
• Ad-related tracking: Google AdSense may use cookies and web beacons.

Alternatives

For a broader category comparison, see Image Vectorization Software.

• Adobe Capture is the better pick when you want Android or iOS access; its free app includes a free Creative Cloud membership with 2GB storage, with optional extra 20GB at $1.99/month.
• SVGcode suits users who need Android, web or Windows availability and a free, no-login plan.
• AI Vectorizer offers web and API access, but its free tier allows two Classic conversions per rolling 24 hours, caps files at 15 MB, adds a watermark to free SVG exports and retains files for 48 hours.
• ImageTracerJS is an alternative across API, self-hosted and web deployments.
• Vectorization.eu provides web and API access with a free online tool and a free trial on its subscription option.
• Vectorization.org allows up to 10 MB and 3000×3000 pixels, with SVG, EPS, PS, PDF and DXF output.
• Vectorizer supports up to 20 files at once, requires no registration and deletes data after one hour.
• WinTopo is the Windows alternative for users who prefer installed software.

Verdict

Autotracer is a sensible free choice for occasional browser-based raster conversion when no account and a short file-retention window matter. Its format range and color controls are useful, but the 6 MB/5000×5000 limits and likely cleanup work are the main reasons to choose a different tool for large, automated or presentation-ready projects.
