Image Quality

Quality only affects JPEG and WebP outputs. Higher numbers retain more detail at the cost of file size.

Edvoa in the rendering path

Edvoa converts with Core Web Vitals in mind. The default web-delivery target is WebP at quality 85, which gives ninety percent of the byte saving with one percent of the developer cost compared with AVIF. Encoding speed matters because most of our Italian publisher clients hit the encoder during their CI pipeline, and the build budget is real.

If your stack already absorbs AVIF’s build-time cost, switch in the advanced panel and Edvoa will use the AVIF encoder for that conversion only. The default stays at WebP because that is what produces the predictable LCP improvement on the Lighthouse mobile profile we measure against. Files older than twenty-four hours are swept; we do not log or sample image content for analytics.

Use it in five seconds

  1. Drop the source asset into the upload zone. Edvoa accepts everything from HEIC capture-files to legacy BMP archive files.
  2. Pick WebP from the format menu. It is the default for a reason: small encoder cost, large byte-size win, universal modern browser support.
  3. Set the quality slider to 85. That is the figure we use for hero images on Italian publishing sites and survives CDN derivatives without further losses.
  4. Press Convert. The Milan worker assembles the response without buffering the entire batch, so each file becomes available the instant it is encoded.
  5. Download the WebP, drop it into your responsive <source srcset> entry, and watch the LCP figure improve.

Technical handbook from the Edvoa team

The following sections extend the quick steps above with the engineering detail we would give to a colleague. Edvoa Web Converter is built around WebP-first, performance-tuned delivery for modern websites; 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.

Format selection matrix

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; Edvoa 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 Edvoa are suitable for proofing and lightweight document assembly, not for replacing a professional pre-press workflow.

Colour profiles and metadata

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.

Quality slider semantics

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 Edvoa 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.

Security and retention

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 team@edvoa.com with your jurisdiction and volume.

When Edvoa conversion is the wrong tool

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.

Convert with Core-Web-Vitals headroom

WebP-first by design

Default destination format is WebP at quality 85, the figure that produces predictable LCP wins on the Lighthouse mobile profile.

Encoder-cost conscious

AVIF is available behind a toggle but stays opt-in; we know the build budget on Italian publisher CI is real.

No render-blocking JS on conversion

The conversion surface is HTML-first; Core Web Vitals on the Edvoa pages themselves stay green on the throttled-mobile profile.

CDN-friendly URLs

Download URLs survive caching cleanly; cache busts only when the conversion settings genuinely change.

Performance lab notes

What our Milan team gets asked

Which image formats can Edvoa convert between?

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.

Is there a file size or batch limit?

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 team@edvoa.com for guidance.

Are converted images stored on the server?

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.

Why does WebP look smaller than JPG at the same quality?

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 Edvoa uses WebP as its preferred output for web-facing assets, especially when web optimisation, Core Web Vitals and modern delivery formats matters.

Can I convert PDF files into images?

The current public version of the Edvoa 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.

Does the quality slider affect lossless formats?

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.

Can I convert images on a mobile device?

Yes. The interface is fully responsive and works in any modern mobile browser. HEIC photos taken with iPhones can be uploaded straight to Edvoa and converted to JPG or WebP for sharing.

Does $short add a watermark to converted images?

No watermark, ever. The output you download is exactly what the converter produced, with no logos, attribution overlays or banner stripes added.

How is the file integrity protected?

All traffic between your browser and Edvoa 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.

Does Edvoa support CMYK or print-ready PDF workflows?

The public Edvoa Web 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 Edvoa for intermediate raster normalisation before handing off to a print partner.

Can teams standardise on Edvoa presets?

Yes. Many Edvoa 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.

What happens if Imagick on the server lacks a delegate for my format?

Some rare encoders depend on optional ImageMagick delegates. If a format is greyed out or fails with a clear error, e-mail team@edvoa.com with your Edvoa Web Converter domain and we will confirm which outputs are enabled on that host.
