Afsod’s converter was lifted out of an in-house image pipeline that used to run nightly across thousands of marketplace listings in Berlin. The properties that matter to enterprise users — deterministic filenames, audit trails, predictable CMYK-to-sRGB normalisation, MIME validation, idempotent retries — are all present, but exposed through a deliberately minimal interface so that an agency intern and a senior pre-press operator hit the same single “Convert” button.
Bad files do not abort a multi-image batch; they fail individually and the rest finish. Conversion settings round-trip via download URL parameters, so you can rerun the same conversion deterministically tomorrow. Files leave our infrastructure within twenty-four hours and we sign a written DPA for German Gewerbe customers who require it.
The following sections extend the quick steps above with the engineering detail we would give to a colleague. Afsod Pro Converter is built around batch-reliable, format-stable enterprise conversions; every recommendation below is written against real workloads, not generic marketing copy. If anything conflicts with your in-house policy, your policy wins — but if you are starting from scratch, this is the baseline we ship in production.
JPG is the default interchange format for continuous-tone photography on the web and in most CMS pipelines. It does not support transparency; semi-transparent PNGs flattened to JPG acquire a flat colour background (usually white). PNG is lossless and should be chosen when you have hard edges, UI screenshots, diagrams or alpha channels. WebP offers both lossy and lossless modes and typically beats JPG on byte size at the same perceived quality; Afsod prefers WebP for outbound web assets when the destination stack supports it. GIF should be reserved for legacy animation or extremely constrained environments — for static graphics, PNG or WebP lossless is almost always superior. BMP and TIFF are archival and print-interchange formats; they produce large files and are inappropriate for browser delivery but excellent for hand-off to a pre-press partner. HEIC is the default capture format on many modern phones; converting HEIC to JPG or WebP is the standard path before uploading to web platforms that do not yet parse HEIC reliably. PDF is a container: raster pages embedded in PDF through Afsod are suitable for proofing and lightweight document assembly, not for replacing a professional pre-press workflow.
Our Imagick-based pipeline reads embedded ICC profiles where present and aims to produce outputs that decode predictably in sRGB-centric browsers. Wide-gamut sources (Adobe RGB or ProPhoto) may be perceptually compressed when targeting sRGB — that is expected behaviour, not a bug. EXIF orientation tags are honoured on read. IPTC copyright and caption fields are preserved on formats that support embedded metadata in our build configuration; if you rely on a specific metadata block for legal reasons, spot-check the output in exiftool after first use.
The quality control affects only lossy codecs (JPG, WebP lossy). It maps to encoder-specific quantisation tables — not to a literal “percentage of pixels kept”. A setting of 80 is the Afsod recommended default for web photography; 90 for hero images and portraits where banding is more costly than bytes; 95+ should be rare and usually indicates that the asset should have stayed in PNG or TIFF until final delivery. Lossless targets ignore the slider by design.
Uploaded files are written only to a quarantined temporary directory with regenerated names. Path traversal attempts are rejected at validation. MIME sniffing via finfo is combined with extension checks. Working files and derivatives are deleted automatically within twenty-four hours. We do not train models on your content, sell thumbnails, or fingerprint files for advertising. If your organisation requires a Data Processing Agreement, contact contact@afsod.com with your jurisdiction and volume.
Do not use the browser converter for medically regulated imaging, forensic evidence chains, or mission-critical print colour proofing without independent validation. Do not batch confidential material from an unmanaged device on a shared network without VPN discipline. For anything requiring CMYK separations, spot channels, or ink-limit profiles, stay in desktop pre-press software until the final rasterisation step.
Our converter accepts JPG, JPEG, PNG, GIF, WebP, BMP, TIFF and HEIC sources, and exports to JPG, PNG, GIF, WebP, BMP, PDF, PSD, AI, TIFF and HEIC. PSD, AI and HEIC outputs require Imagick to be compiled with the matching delegates on the server, so check the about page if a particular format does not appear in your dropdown.
Each upload is capped at the size displayed on the upload area, which by default is 5 MB per file with up to five files per batch. The limit is configurable per domain. If your file is larger, please resize it first or contact us at contact@afsod.com for guidance.
Originals and converted output files are written to a temporary directory and automatically deleted after twenty-four hours by a sweeper that runs on every request. We do not keep copies, hashes or thumbnails of your files for analytics, advertising or any other purpose.
WebP uses a more modern compression algorithm than JPG, so it usually delivers similar perceived quality at twenty to thirty percent smaller file size. That is why Afsod uses WebP as its preferred output for web-facing assets, especially when enterprise-grade reliability and reproducible workflows matters.
The current public version of the Afsod converter focuses on raster-to-raster and raster-to-vector container conversions (for example JPG to PDF). PDF-to-image splitting is not exposed in the user interface yet, but the underlying Imagick stack supports it. Drop us a note if this is something your team needs.
No. PNG, GIF and BMP are lossless containers, so the quality slider has no effect on them. The slider only changes the JPEG and WebP encoders, which use real lossy compression.
Yes. The interface is fully responsive and works in any modern mobile browser. HEIC photos taken with iPhones can be uploaded straight to Afsod and converted to JPG or WebP for sharing.
No watermark, ever. The output you download is exactly what the converter produced, with no logos, attribution overlays or banner stripes added.
All traffic between your browser and Afsod is encrypted with HTTPS. The server-side handler validates MIME type and extension, regenerates the file name to prevent path collisions, and limits acceptable formats to a curated whitelist.
The public Afsod Pro Converter converter targets sRGB-centric web and office workflows. CMYK separation, ink limiting and certified print PDFs require desktop pre-press software. You can still use Afsod for intermediate raster normalisation before handing off to a print partner.
Yes. Many Afsod users document three internal presets (web hero, thumbnail, archive) and share the quality and format numbers in their design-system wiki. The tool intentionally stays minimal so those presets stay stable across browser updates.
Some rare encoders depend on optional ImageMagick delegates. If a format is greyed out or fails with a clear error, e-mail contact@afsod.com with your Afsod Pro Converter domain and we will confirm which outputs are enabled on that host.
Afsod is batch-reliable, format-stable enterprise conversions. Built by a Berlin-based image automation team, the toolkit you see here covers the three jobs that account for almost every routine image task on the modern web: converting between formats, resizing for a new container, and cropping to a final frame. Everything happens on a single page, with privacy by default and no account required.
Afsod Pro Converter exists to turn fragmented image pipelines into a single predictable workflow. Our priority is always enterprise-grade reliability and reproducible workflows, and the tools below are tuned to deliver predictable, high-quality results for agencies, e-commerce teams and content departments across Europe.
