Što je EPS?
Profesionalni vektorski format temeljen na PostScriptu za tisak i dizajn
EPS (Encapsulated PostScript) je vektorski format koji je Adobe stvorio 1987. godine. Temelji se na PostScript jeziku za opis stranica i može sadržavati vektorsku grafiku, tekst i ugrađene rasterske slike.
EPS datoteke su neovisne o veličini — mogu se povećavati ili smanjivati bez gubitka kvalitete. To ih čini idealnim za logotipe, ilustracije i tiskarske materijale.
U modernim radnim procesima PDF i SVG postupno zamjenjuju EPS. Međutim, EPS se još uvijek široko koristi u tiskarskim i dizajnerskim procesima.
PostScript is a full programming language, not just a data format. An EPS file contains actual executable code — moveto, lineto, curveto, and fill commands that draw shapes, plus control structures for fonts and color. This is powerful but also a security concern: malicious PostScript can execute system commands on some interpreters. Ghostscript, the most common open-source PostScript renderer, has had multiple critical CVEs (CVE-2023-36664 was a remote code execution flaw). Don't open EPS files from untrusted sources in older software without sandboxing.
EPS files follow DSC (Document Structuring Conventions), a set of comment-based metadata rules that start with %%. The first line is always %!PS-Adobe-3.0 EPSF-3.0, which identifies the file as EPS. Structured comments like %%BoundingBox define the artwork dimensions, %%CreatorTool records the originating application, and %%DocumentFonts lists required typefaces. The TIFF preview, when present, is stored as a binary header before the PostScript code — which is why EPS files sometimes look like binary garbage when opened in a text editor.

Kada koristiti EPS
- Logotipi i brendirani materijali za tisak
- Profesionalni tiskarski materijali
- Razmjena vektorskih ilustracija između programa
- Kompatibilnost sa starijim tiskarskim procesima
- Distribucija stock grafika
Prednosti i nedostaci
Prednosti
- Neovisan o veličini — skaliranje bez gubitka kvalitete
- Podržava CMYK boje — idealan za profesionalni tisak
- Široko prihvaćen u tiskarskoj industriji
- Može kombinirati vektorsku i rastersku grafiku
- Podržavaju ga gotovo svi profesionalni dizajnerski alati
Nedostaci
- Ne prikazuje se u web preglednicima
- Datoteke mogu biti velike
- PDF i SVG ga zamjenjuju u modernim procesima
- Nema pune podrške za prozirnost
- PostScript sigurnosni rizici
Kompatibilnost
EPS otvaraju Adobe Illustrator, Photoshop, InDesign, CorelDRAW i drugi profesionalni alati. macOS Preview također može prikazati EPS. Web preglednici ne podržavaju EPS.
EPS u usporedbi s drugim formatima
- EPS i SVG
- Oba su vektorski formati. SVG je za web i radi u preglednicima. EPS je za tisak i podržava CMYK.
- EPS i PDF
- PDF je moderni nasljednik EPS-a. PDF podržava prozirnost, više stranica i bolju sigurnost.
- EPS i AI
- AI je Adobe Illustratorov format. AI je bolji za uređivanje, EPS za razmjenu između raznih programa.
- EPS vs PSD
- PSD is Photoshop's raster format for pixel-based editing with layers. EPS is primarily a vector format for scalable graphics. They serve different purposes: use PSD for photo editing and compositing, EPS for logos, illustrations, and print-ready vector artwork. PSD can embed vector paths but isn't truly vector. EPS can embed rasters but isn't ideal for photo editing.

Često postavljana pitanja
- Kako otvoriti EPS?
- Koristite Adobe Illustrator, Photoshop, CorelDRAW ili macOS Preview. Inkscape (besplatan) također otvara EPS. Ili prenesite na My File Tool.
- Koja je razlika između EPS i AI?
- EPS je kompatibilniji za razmjenu. AI je format Illustratora koji čuva sve slojeve i efekte.
- Mogu li koristiti EPS na webu?
- Ne, preglednici ne podržavaju EPS. Za web pretvorite u SVG ili PNG.
- Kako pretvoriti EPS u PNG?
- Prenesite EPS na My File Tool i odaberite PNG. Prva datoteka je besplatna.
- Why is my EPS file showing a low-quality preview?
- EPS files contain a low-resolution bitmap preview for display purposes. The actual vector content is full quality but requires PostScript interpretation. Open the file in Illustrator or export it to see the true high-resolution output.
- Are EPS files safe to open?
- Be cautious. EPS files contain executable PostScript code, and vulnerabilities in PostScript interpreters (like Ghostscript) have been exploited for remote code execution. Don't open EPS files from untrusted sources in desktop software. Converting them online (like on My File Tool) is safer because the server handles the PostScript rendering in a sandboxed environment.
- Can I edit text in an EPS file?
- It depends. If the text was saved as editable outlines (which is common for logos), you can manipulate the letter shapes but not change the words. If the original fonts are embedded and your software recognizes them, you can edit the text directly. Adobe Illustrator gives you the best chance. Inkscape can open EPS but may not preserve all text formatting.
- How do I convert EPS to PDF?
- Adobe Illustrator does this natively — open the EPS and 'Save As' PDF. Ghostscript can batch-convert from the command line: gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=output.pdf input.eps. Or use My File Tool's EPS converter for a quick browser-based conversion without installing anything.
